Well turns out my SS/TC is tuned.

I need more info incase I need warranty work. My friend with a 4 door SS/TC said I dont have the GM stage tune just by looking at my sensors

Im sure the previous owner had to be on here.

I had it delivered from Allentown, PA from a BMW dealer.....anybody? It has blacked out tails...IDK what else to mention....

 

u could always flash it back to stock and put a tune u know something about in

 

Where can I get a stock LNF tune just incase I need to go in for some warranty work? HPtuners tune repository?

Anyone know how to tell if Im HPtuned or Trifecta?

Curious....with the GM stage tune one must upgrade to a 3bar sensor correct? So if Im on stock sensors but pushing up to 20 psi is that bad?

Sorry for so many questions but Im just really worried because I was under the impression when I bought this car it was 100% stock....and it will be a daily driver

 

You're stock MAP and TMAP sensors will be fine on 20 psi. Usually the Trifecta tunes are the stealth tunes. Try WOT boosting in 3rd gear with the cruise control on and off and see if your boost pressures change between the two settings. If it doesn't change, try doing the same thing with the traction control on and off. If you have two different boost levels with either of those switches, you have a Trifecta stealth tune.

If you know anyone with HPTuners, you can see if they can connect to your ECM. If they can, it's likely an HPT tune. HPT won't connect to an ECM that has the Trifecta software on it.

You can pay the dealer to flash you back to stock, but chances are they will flag you.

 

I have hptuners. And sorry for being a newbie but this is my first Cobalt so I still dont even know how to turn the Cruise control on....LOL I know but bear with me here.

And yes Im worried about getting flagged at the dealer. Heck the car only has 15k miles on it.

 

cruise control is the big button on the left side of the steering wheel, a little orange light will illuminate when its on

 

Well I just went outside and tried to read the PCM via my HPtuners and it completed everything up until step 5...Reading Entire VCM....and it failed.

I dont need credits just to read it right?

 

no i don't believe so. it might be trifecta tuned, so the ECM is locked so you can't read his tune and copy it per say.

 

You can use Scanner to scan the vehicle without having the vehicle/year unlocked.. It sounds like you were Trifecta tuned.

 

So if it is trifecta tuned is it stealth tuned or is that extra or watever?

Yes I was able to do the scanner but not the editor.
