So i got a 09 ss/tc a little over a month ago and it had GMS1, Dejon Upper Charge Pipe, Dejon intake, and Muffler delete. I added a 3" Catless DP a couple weeks back. Anyways i am spooling around 22-23lbs of boost and have verified with Vince there is no Trifecta tune on my car. I recently ran a Charger R/T with intake and exhaust 5.7L Hemi which stock is suppose to be 340HP. I put a car on him easily. Is the cobalt that beast with that little of mods or could there be a tune in there maybe HPT? opinions?

 

The R/Ts are pretty slow in comparison to the SRT8. 340hp is at the crank I'm guessing and they are pretty heavy.

 

If you're boosting 24, I'd say you have a tune.

 

I get up near 23 lbs whenever i go full out so it makes me wonder if there is a HP tune on the car it just seems a little faster than GMS1 hp ratings

 

Yes theres a tune. If you are running all those mods and arent throwing a code and boosting over 20...........ya man you have a tune. When i bought my car the guy told me up and down it never had a tune and was only gms1, found out when i had it tuned last sunday it did have a tune on it. **** happens people lie........but i advise getting a good tune from someone reputable so you know its not a shitty tune like i had on mine

 

Is there any way to run the VIN through HP tuners to see if it has been tuned by the program?

 

Well depends. When I was stock I'd hit 20psi because the altitude compensation. I'm tuned at 23psi but I hit 25 just because the altitude or a tuned spike not sure. But for sure when I was stock I'd hit 20psi on wet days.

 

Woah Chirs!!! Now we are on the same forums! haha.

You go and buy a cobalt and im thinking on buying an srt. lol. (for the ol lady tho).

 

gms1 boosts 22-23 psi

 

Lies, you will not throw a code with bolt on's unless someone installed them wrong. I ran GMS1 with full bolt on for several months and did not throw a code. As for 24 psi, when I was on GMS1 I would spike 24 on rare occasion, it could just be a freak thing. I would say your tuned if you were holding 24 PSI though because I know that on GMS1 it would hold 22-23ish. As for running that car, ours is close to 1k lighter and at the wheels that car is around 290hp. Big advantage with GMS1 and bolt ons.

 

ya im kinda confused too, not sure why he is spiking 23-24psi, but i know the Dejon SRI sucks ass and throws off the fuel trims bad, so i was hoping he was trifecta tuned so i could get with vince but he said he wasnt, i want to make sure his AFR's arent wacked out because of the Dejon intake
