Most were running ~22 psi a couple were on 24-27 psi. IMO even the newest tunes are too rich. That just sacrifices power, combustion flame front efficiency (the reason DI is so great and why it makes more power using less fuel) and fuel mileage as well. Because the tune is switchable normally you are not running it all the time. Meaning any issues that might surface will take much longer to do so.

 

All this Trifecta stuff scares me, but I have never had any issues with mine at all with misfires but im only running like 22 PSI

 

Didn't your car make only 260 whp with your first Trifecta tune? Brian was saying something about that before.

 

It did but it was my fault because I didnt datalog it like I should have, (Im new to tuning and at the time I didnt know at the time). But I have it now at 306 HP and 352 TQ with no issues



BTW, whatever happened to Brain's car?

 

It is still running like crap. There is something major broken on it and the dealership he uses has yet to find the issue. His car runs like crap compared to all the others and I feel bad because there is nothing I can do to fix his issue. The car randomly misfires badly and the compressor surges as it misfires. The car knocks badly even on basically stock timing and a 12.7 A/F. I think he has 1 or more cracked pistons or possibly a bad coil pack but I am not sure.

 

trifecta!!!

 

Holy **** that sucks ass, hopefully Ferman warranties whatever it is for his sake and that is the same dealer I go to.

 

I plan on running a MBC now tho and bringing it back to 25ish. Im sure running it this hard and continuing to will def lead to something bad happening LOL.

I need to stop messing with this car...lol

 

I thought you were at 25 ish with the pill in there? I finally stopped messing with my tune today. I cannot ask for anymore performance or mileage out of this car. 40 mpg hwy and goes like hell. You have almost twice the miles I have and my car is over 18 months old now. You must drive a lot.

Yeah it sucks I feel bad for him.

 

No, I just said what would get you about 25ish. Im running 28-30 at times. But you will only see that high if you do WOT in 4th or 5th down low. 3rd was 26-27 spike, held 25ish most of the pull.

I drive ~100 miles a day on the car.

 

That is what mine does. Spikes 25-26 psi normally holds 24-25 until about 6K.

 

Does it stay the same for 4th and 5th?

 

I am not sure because I have not gone WOT in 4th or 5th in a while. My clutch does not like that very much LOL. It does see 24-25 psi in 2nd now with the MBC in series with the BCS.

 

So its likely you will see 28-30 down low in 4th and 5th. I get similar results in 1-3.

 

Well,
I've stayed quiet long enough. As a TriFecta dealer, let me point out a few things.

First of all, the same mystery problems with Trifecta keep being posted by the same members. As this community grows and new members enter and look for information, they are constantly being told the same thing over and over and over.

Let's cut to the chase:

as a dealer of TriFecta tunes, and one who has sold over 300 to members of this forum and other forums, let me tell you all about the problems reported to me... Hmmm? Give me a moment to think........ You know what everyone??? In over 300 TriFecta tunes I have sold, I have not had a single problem reported to me by a single customer. If the TriFecta tune was causing engine failures, broken pistons, mis-fires, etc, I would certainly have been made aware of it by now. And I most certainly would have dropped TriFecta.

As many of you here are new to the community and are not familiar with TriFecta, let me offer you all some insight into who they are, where they started, what they do and what they have done.

1. The owner of TriFecta is Vince Geglia, a former Microsoft programmer. He's very modest, very quiet and extremely intelligent. I had to find out on my own that he wasn't just a programmer at Microsoft, he was pretty much in charge of major software development.

2. He got bored at Microsoft and quit to pursue a passion of his, cars... He loves what he does.

3. Since Vince loves what he does and is capable of writing code, he developed his own unique software language to allow his hardware to communicate with the cars computer.

4. No other company or individual walking the planet, yes I said the planet, is capable of tuning the LNF the way Vince can.

5. Vince has un-locked the fuel tables when everyone else failed.
6. Vince has been able to make the tune un-detectable by GM when others just dream about this ability.
7. Vince has been able to up-load more than one tune to the pcm.
8. Vince has been able to allow the driver to choose between tunes, on the fly, with the push of a button.
9. Vince is capable of remote dyno tuning when others have to be present.
10. Vince has been able to re-map the stock sensors to work with higher boost, even when GM couldn't. Vince can up-load the GM Stage Tune with stock sensors.

11. Vince is currently writing code to allow the driver to determine, and set, the rpm range for launch control. On demand whenever they choose. (Yeah, you heard that correctly!!!).

So with all of the innovation Vince of TriFecta is capable of, all of the areas of the stock pcm he is able to access when other companies and individuals are left clueless, being able to create his own software language, do you guys actually believe he is not capable of simply setting the air/fuel ratio correctly?

Do the math everyone, something just doesn't add up. TriFecta is under attack, as usual, by his competitors who, simply stated, have no possible way of competing with him on the same level. They don't have the capability. So they post false info, constantly state the air/fuel ratio is wrong, try to allude to all the "problems/issues", etc. When the smoke clears and the dust settles, where are all of the actual owners of these cars we keep hearing about?

In a nutshell, those same individuals who keep taking stabs at TriFecta, are tuners themselves. Hence they are TriFecta competitors thus being biased. Rather than paying to become a supporting vendor on this forum and offering their own tuning services, they instead pose as "just trying to be helpful" members while casually letting the fact they tune on the side, slip out...

Do your own research and you will see the same member(s) posting the same bogus problems about TriFecta tunes. It simply isn't true.

I hope this sheds some light in this extremely darkened area of the forum.

 

^ Dan thank you for clearing that up, all the research I have done on Trifecta has been positive until I read through this thread. Nice to know some of the background about Vince and Trifecta in general. I think I'll be purchasing a Trifecta tune in the not too distant future.

 

Just make sure you keep boost levels well within the tollerances of the stock turbo and rings/seals if you go this route .

 

Not an LNF

But Trifecta FTW...Just got done with my tune for my TVS. Vince was very helpful and the process was more than easy. At first I was a little worried as Vince was very open in saying he has never worked with tunning for 79lbs inj. You can tell he has a methodical approach at looking at datalogs which comes for his back ground I guess. No part of the data logging or updating the tune for the larger injectors became an issue. Vince was very informative and advised on safe numbers instead of just trying to get the most hp from the tune, this was good for me as i know nothing about tunning this is my first modded car. My overall experience rating would have to be 10 out of 10 (the only other company to get a 10 from me was Discover Card). The knowledge that Vince had, the easy of the overall process, and the quick review and update of datalogs made the whole experience a 10. Also Vince went out of his way to rush the original shipment of cables and instructions to me the day I ordered so I would get them the next day as the car is my dd. Thanks Vince this was above and beyond my expectations.

Just my thought of Trifecta

 

Let them do their own research. There have been several posts and threads on here. You are lying if you say there have been no problems reported. Maybe no one told you but that does not mean no one has reported any problems. I know of several people with issues on here. Let me make this perfectly clear you may think I am posting false info fine but I know I am not and that is all that matters to me. Sorry to burst you bubble but I do not attack Trifecta because he is supposedly my competition I do so because I do not agree with the A/F he uses. I do not tune solely for the money. There are at least 50 LNF owners on here and other forums that I have helped tune their own cars. Most of whom have not paid me a cent. I have helped 6 in the last 5 days. So Dan keep questioning my motivation if you wish but you could not be more wrong about me. I tune because I love doing it not because it makes me money. I started tuning because I made the mistake of trusting someone who was an "experienced tuner" to tune my car for me. I know first hand what running an LNF really rich does to the motor because I have experienced it for myself. What is a "safe and efficient A/F" on a SMPEFI motor is not on a GDI motor like the LNF and vise versa. Anyone on here with an LSJ think it is good to run a 10.0 A/F on their car on gasoline? Same principle. Just say no to hosing your cylinders down with gasoline!!!!

 

just seems weird that someone who is obviously knowlegable about tuning would purposely run someone rich and chance them cracking a piston (speaking of how can having some extra gas in your cylinders crack a piston?? and I thought a lean tune would end up causing high boost levels??!!) or destroying their car?? why would someone like vince do that? he can obviously properly adjust a/f ratios with a push of the button. so he wouldnt be doing it cuz he doesn't know any better which leaves the aspect of benefits. would running our lnf cause a better tune? I guess not, its a DI motor, are u saying vince doesn't realize that? if he is running rich he has a good reason for it. maybe running lean with his tune is worse for the car, who knows, let him explain.

 

Vince is an extremely talented software engineer. He is very good at what he does but IMHO he is not the worlds greatest tuner. There is absolutely no benefit to running an LNF richer than 12.6 A/F. It sacrifices power, durability, and fuel efficiency. I believe he tunes them rich because he believes that 11.7-12.2 is a safer A/F to run. It is a perfect A/F for an LSJ or other SMPEFI FI engine. Extra fuel means lots of carbon buildup in the cylinders which causes hot spots on the pistons and that weakens them over time. Look how much soot these motors produce on the stock tune and it runs 14.0 A/F until 4500 rpms. The richest the stock A/F ever goes is 12.9 until the cats reach 1700* modeled temperature. Also, at higher rpms the shear amount of fuel need to maintain an A/F of approx 11.8 means that the injector pulse width exceeds 5.4 mS. Once that happens the injection cycle carries over into the compression stroke and the fuel wets the crap out of the piston and most importantly the rings. Once the spark happens. The combustion flame burns very slowly and erratically and all that excess fuel on top of piston rings ignites which puts tons of stress on the ring lands causing them to crack over time. You are basically inducing a mild hydrolock with that rich of a mixture on a GDI motor.

 

so the lower the a/f number, the richer?? what does the stock lnf run , as far as a/f ratio?

 

vince doesn't tune his lnf's to high 11's low 12s anymore FYI term...

 

I used to have the trifecta tune that was rich. I swear if my rings go out I'm going to be so pissed lol

 

The recent dyno sheets show it still going into the 12.2 to 11.8 range up in the higher rpms.

Yes lower means richer. Stock tune runs 14.0 A/F in the midrange and 13.0-12.9 A/F up top. 14.0 is a little lean at WOT IMHO. I think GM used a midrange mixture that lean to limit torque output. Anything leaner than 13.2 or richer than 12.6 is a waste IMHO.
