Trifecta Tune equals 80wtq/32whp gain. Boost stats 18.4 psi...We are not sure what was going on there...but I think its where they picked it off from. A/F was 11.8-11.9 with a nice curve. Plan on doing the GMPP Tune the same way if it ever comes outs (lol)

Some might say this or that about the dyno curve.....There was a stock w/ K&N drop-in (02 I think he said) C5 Vette just before my car, put down 314whp/339wtq

 

too rich.

 

Yeah you wanna be around 12.6 to 12.8

 

This also puts to rest anything people were saying about stock tune being rich or lean compared to a tuned (in this case, Trifecta) setup. Nice baseline as a control variable. I like it.

Any chance we can dial in some of the secrets learned here, apply to the GMPP tune, and see something even greater (because of the increased boost limit)?

 

Well I plan on getting the GMPP if it ever comes out to put it through the same test...Reason I'm running this. But first it would be GMPP intake (what/ever that is) w/ trifecta tune, then go get the GM tune and redyno. I can get the GMPP at dealer cost...But once I do that I'm stuck on the GMPP until I get a tune over that. (2 ECM's helps)

I had a call from Vince @ trifecta..I'm happy w/ my numbers. If he changes anything up down the road I will go with that. 342wtq is nothing to laugh about....which explains the ability of my car to spin in 3rd @ low rpms and flooring it. The car is dying uptop...It was 93 w/ 80% humidity......I'm sure most of those big numbers are done in ideal conditions....and the cooling fan died (he warned me it was acting up and asked if I wanted to dyno another date). After they turned it off so I can put in the other ECM it wouldnt restart....so no air flow moving over the engine bay other then the breeze through the shop

 

Yeah, the problem I see with the GMPP kit is the fact that there's really no going back after you do it since they pretty much do a hackjob to your piping and the old OS can't even read the newer sensors. I'm guessing a new line of tunes will have to come out that support the newer OS, huh... something like a "Trifecta 2"?

You'll need to flash you other ECU with the newer OS as well to maintain compatibility.

Isn't the intake now coming out later, after the tune, to give them more time to troubleshoot the problems they were having with it? Your plan may have been foiled by GM. I don't guess it would hurt to do the tune first and then get the intake, especially if you're wanting to be one of the first and can't afford to wait around on the intake. That's probably the order most people that adopt it early will do it in anyway (if the intake is indeed coming out a bit later). Plus, I don't know why people would do the intake but not the cooresponding tune, since it's not like the tune's a warranty issue and that they'd be holding out on tuning it and just doing bolt-ons in the meantime. A few maybe, but I just don't see a ton doing that.

 

Nice numbers!!

 

X2.
I have told many others on here that tune is way too rich mostly low 12s and high 11s. Needed to be around 12.9 in the midrange and 12.6 up top. Boost seems too low too it is supposed to be commanded at 21.5 psi.

 

Ahhh it is just fine, there is a reason trifecta is making some of the highest numbers. They adjust more then AFR and boost

 

:facepalm:

key word being some.

 

All hail mighty tune god

 

His tune has yielded some fast track times and thats all that matters....wish they would have leaned the tune out a bit. I got it becuase the ease of not having to have HP tuners and pay out the ass for it. Plus it is safe and conservative is fine for me. Though somebody looking for more could lean the tune out and still be safe.

 

Most stock C5 vettes put down less than that one did, most are right at 305 whp and 320 wtrq depends though. You boost should have been 21.5 psi. I would be wondering why it was so low and your A/F is still a full point too rich. You could easily gain 15-20 whp by leaning it out to 12.9-12.6. Vince must think these cars are port injection there is no way the car will make more power in the 11s. I tried that with my car and I lost 25 whp when I commanded my A/F in the 11s.

 

WERD!

 

HAHAHAH ok well sorry but vince does know we also tested many AFR and made more power at the 11.8, like i said he adjust a lot more then just afr and boost

 

I am just letting you know that I tried just about every A/F setting on my car from 12.9-11.6 and it made the most power by far in he 12.9-12.5 range. Dropping it to 11.6-11.8 from 12.7 or so it went from 307 whp Corrected to 284. It lost 23 whp from being that rich. There is a reason that all other tuners on here including Area47, 1badblueberrySc, Psychostevo and all the others that I am forgetting all run around 12.9-12.5 range. That is where the most power is while still being quite safe. The stage tune HHR are at 13.0 which is a touch too lean and it wont make quite as much power up top at 13.0 but it had to pass emissions. Sherm420s car was in the 10s A/F on the dyno (I was there) because of his Hahn Intake and the Trifecta tune. It made only 248 whp because of that and it is still not right. His car runs fine with the stock tune but the Trifecta tune is causing it to misfire a ton now IDK but something is not right about that tune in his car. Ever wonder why the fastest Trifecta tuned cars are trapping 105-107 and some others. Like boostking and Revhigh are trapping 113+.

 

im sorry, when my cars all produce higher trap speeds and lower et's at the track than canned cars. i think that says something for myself. so if you feel the need to be blind to the fact you have a canned tune. be my guest.

whats the cam angle's at 5500 rpms on the intake side on the trifecta tune?

a great mystery?

everyone on here is quick to jump zzp/intense's **** about lsj tunes. what do you think you're doing with the nut suckling of trifecta's?

 

how much do you charge for a tune?

 

terminator2 pass me the popcorn... this is gettin interesting

 

11.8 afr that he tested made the most power on a DI car? oh im sorry, i forgot. he is YOUR tuning god.

come back to reality for once.

 

subd

 

Yes it is.

 

On the bright side, we'll at least get a few things straight on AFR.

Next upcoming thread battles: Spark Advance and Cam Phasing haha

 

That is what I was saying too. I lost almost 25 whp try to run it that rich.

 

don't screw up and stick the decimal point in the wrong spot. fuel will roll out the ass end like a cummins I-6!
