well you have the same flat spot in your graph as well at the same RPM as me in teh HP graph. so im not worried about that n e more that must be in the tune. However still doesn't explain where all my torque is

 

Yeah the tq difference is odd... im sure theres an explanation

 

When you get the Trifecta tune it's truly undetectable... I know of cars personally that have gone to the dealership tuned and never had a problem. One car in particular had a faulty intercooler replaced at the dealership and they said "good thing you didn't have a tune on this car, we checked for one."

Far as dyno numbers, unless the people comparing numbers have been on that particular dyno then the only true comparison that could be made would be from stock airbox to K&N SRI; because each dyno is different from the next one.

 

I noticed the stock graph is UNCORRECTED and GM1 is CORRECTED SAE.
SAE corrected shows about 4-5 HP LESS vs uncorrected.
Also, the GM1 tune is designed to have a much *peakier* curve than stock...falling off rapidly after 4500 RPM

 

yeah the day that i did my first run (uncorrected) was misty and foggy which the correction would have worked in my favor and added HP. last night was hot n humid... even with the fans on my IC the IAT was like 95-100F and it was actually like 85F out or so. Humidity was probably 70% (its humid as **** here!). that being said the true numbers last night were actually only a hair higher like 1 - 2 HP and 1 - 2 wtq. not that big a difference at all.

says the trifecta dealer . no offense haha just kinda funny is all. but honestly even tho my dealer here is more or less clueless i still wouldn't wanna risk it + like i said i heard some dealers putting cars in ESC off to check to see if there is a tune. not sure how they can tell aside from driving it but still. not a risk i really wanna take on a car so new.


On another note... basic math tells me over my stock dyno i added 58 lbs of wtq and 36whp... these gains seem semi normal for GMS1... however numbers still aren't quite what i expected... + the 15psi at 4500 ish rpm is a little worrisome.

 

No offense taken... but if you'd like names on here for someone to speak to you about this then I'm more than willing to have you talk to them directly. Anyone who has ever dealt with me either through here or in person will be able to tell you I'm not here to BS anyone, just to help. I do understand your concern though and that's more than acceptable.

 

To start things off, before I got my car tuned I ran a dyno-pull with my stage 1, mods in sig minus degon piping. My car flat lined 4300-4800RPM.

This is on ZZP's dyno witch is a Mustang dyno

282hp 5500rpm
306tq 4300rpm

 

nice numbers. I'd be more than happy to trade ya especially where that was a mustang dyno and mine was dynojet.

for sure, i hear where you are coming from. my only concern is over the last few days i have been cruising around the forums lookin at GMS1 dyno numbers and mine appear to have the lowest wtq of n e i have seen... however when you compare the curves they are almost identicle just with my TQ stopping short... weird... im gonna make sure everything on the intake and CP's are good n tight n do some more pulls around town tonight on the RPD its worth noting that when i was crusing around last night as well that my boost dropped back to 15psi again 2 more highway pulls in a row i was wrong on the RPM window tho its actually closer to 5 k where it shuts down. is this normal? i thought it should pull 20 psi straight to the red line. let me know

 

I just got my car back from the dealer after they put a whole 5th gear assembly in. They said they couldnt get any data from the computer because of my Dual Intercepters blocking it somehow, unless they were to dumb to unplug it . Anyone else ever here of this ? Also On Star sent me an email stating they couldnt do the monthly scan because of an unknown device connected to the OBD port.
