Maybe in winter but in summer it can get up into the triple digits with 70% humidity. Summer in florida sucks sometimes unless you like the beach.

 

i was in vegas 2 years ago in my it hit 119 yea it was hot but they dont have the humidity we have

 

Edit I forgot there are technically three correction levels uncorrected, STD, and SAE. If those are his STD numbers they are still low. You dont want to know what my tune made uncorrected I wish I had the sheet for that, it was 258 whp 256 wtrq stock and 315 whp 347 wtrq with just the tune. My numbers are corrected.

 

and I was running 93 octane btw on the dyno day

actually I always run 93. All our premium around here is 93 octane

 

Your numbers are very low then maybe because the tune is a shade too rich, but maybe that dyno reads very low what numbers did you car putdown stock? Was the car knocking or anything?

 

no knock and I dunno about stock. Dammit I shoulda done a dyno run when I was stock. Stupid me

I'll be home today around 7 or 8 and I will scan my dyno sheet and also my A/F graph also. maybe that will help

 

Here is a good way too see how much power you are making. If it is warm out ( over 78* ) Can you spin the tires on your car from a 30 roll in second all the way to redline. If so you have quite a bit of power. If not something needs to be looked at.

 

my boost was very spikey as well. goes up to about 23 real quick then back down to 18-19.

I'll have to see about that 2nd gear pull. It hasn't been 78* here in a while and wont be for a few months lol

I set up my BOV by running the factory line to the VTA BOV and the factory BPV I have blocked off with a vacuum line to the cold side piping which I T'ed into. I am going to try using a block off plate and see if that makes a difference.

 

The BOV will only be an issue when it releases when you shift the mixture will go rich for a second. The ECM adjusts very quickly for that. that tune is supposed to boost 22 psi all the way. It is normal for there to be a short 24-25 psi spike when you first hit it before the wastegate has a chance to open. If you are seeing nly 18 psi that would explain your numbers you will make 25 or so more HP at 22 psi.

 

yeah I think there's something wrong with the tune. When I received the GT tuner from Trifecta Vince forgot to put a tune on it, so he had to email it to me, then I uploaded it, then downloaded it to my car. Maybe something got lost in translation.

The only other thing I can think of is a boost leak.

 

That is probably it. I would contact Vince about the fact that you are seeing only 18-19 psi have him send you a new tune that should take car of it.

 

ok I just emailed him right now. Thank you very much for helping me. I have alittle but of experience with turbo cars but I am just dumbfounded at this one. I really don't think it was the dyno that was off. I have rode in cars that were 320-325whp and 350wtq and this car is definitely not there. the 287whp numbers seem pretty accurate. To be honest it just feels a little but faster than stock but not by much. Hopefully Vince will have the answer. Thanks again man

i talked to Vince and he said it has to do with the intake i am running. The MAF is reading too much air and restricting boost which is why it is limiting boost to 18-19psi. he said try the stock air box which I don't have anymore lol

 

Just spoke to eiuptrycntrl about this on the phone. I'm going to look at his dyno charts later, but the initial suspicion is the intake system. He has the same exact tune that produced the dyno sheet that is circulating the forums

So far I have yet to see an intake system that doesn't cause airflow problems at the sensor (we're still developing the Clear Image intake system because of this). These vehicles are extraordinarily sensitive to reported mass air flow (MAF) at the sensor. Unless the intake system is carefully tuned to produce the exact same airflow characteristics as the stock intake system, boost, ignition/cam timing, and fuel ratio can all be affected.

 

Weird I have the same intake as you and I have no issues with mine the car pulls a little harder with the intake. My MAF signal is not skewed much I do not think because my gas mileage is the same and I have no unusual issues to speak of no CELs because of wacked out fuel trims.

 

Thank god for vince. I would be lost haha

 

You are definately right about the sensitivity of these cars MAF that is why all the homemade intakes throw codes on these cars especially if the distance between the MAF and the filter is changed. I have no issues with my dejon intake though my boost is still the same as when I got the car tuned the A/F may have shifted a little to the richer or leaner side though I will see when I get my tuned touched up next month.

 

I also ordered the intake with the valve cover vent hose. And the hose doesn't exactly clip onto it so maybe that is the problem. Terminator did you order yours with the vent hose? or did you delete it and just put a breather on the hose?

 

In this case it sounds like the fuel is OK, but the unstable boost issue sounds like there may be turbulence at or near the MAF. Could be a leak somewhere, too, sounds like boost is off about 2-3psi - on the test car we saw 25psi peak, settling in at about 21.5-22psi sustained.

 

on the intake i have the MAF is also closer to turbo than stock. Would that have something to do with it?

 

Possibly - any changes in distance, tube diameter, proximity to bends, etc. can all affect how the MAF reads airflow

 

ok gotcha

 

Hey all! I am a bit new to the turbo tuning scene, and really like the Trifecta tune, and all the good I am hearing of it. But, has anyone had any reliability problems? Obviously, with more performance comes more risk of reliability issues, which I am fine with. But, any serious problems to report thus far?

Also, is the tune all I need? I know in VW's there are a few small parts you need to change because they cannot stand up to the heightened boost levels.

Also, if i get the data cable, what do I use to return to stock map? My computer? Or is it the GT tuner? I'm confused how that works.

Thanks in advance everyone!!!

 

As far as i know...there has been no problems! at all.

If you want to return it back to stock at any time it is best to get the Data cable! You can use your computer to return it back to stock.

 

That could be it. I had to take the metal breather tube off and put a rubber hose there because mine did not reach either. If that is leaking air than the MAF is not metering that air and that would cause a lean condition. Make sure you seal that leak It could be the problem.

 

No issues at all with the tune i have had it for almost 4000 miles no issues what so ever. What we suggest you get with the tune is boost tubing because of the extra pressure and i recommend a DEJON BPV spring upgrade that will hold boost better. If you get the Data cable i am sure Vince can send you the stock configuration to your laptop so you can switch when ever you want
