I just had my tune done by P&P Tuning here in St. Louis (HIGHLY recommend getting ahold of Ryan for a tune (pnptuning@gmail.com)). My car has Hahn 3" catback and a Dejon SRI. I have a very hard time keeping my car to now spin with teh Continental Extreme Dw's on it. When we data logged the GM Stage 1 tune, it was pulling sometimes up to 4* of timing. He then went ahead and got rid of that. On the GM tune, boost would spike to 21 and fall off to 17-18 in 3rd. Not it holds strong at 22-23. I can't be more happy with what Ryan has done. It is by far the best "mod" you could do for one of these in my opinion (and probably everyone elses). My car has more in it, but we want to save the clutch for now. Ryan also tuned wickedlsj on here and his car will trap 114+ this year along with a z24 cavalier that trapped 135 and went 11.1 (IIRC) on stock computer. Just wanted to say thanks Ryan for what you did for me (Imphat0260)

 

Tune over the Stage 1 is the best way to go

 

yep! I got over 20hp and 30tq on top of the stage onelol

 

Tune. get the gm stage 1 items, minus the tune. and get a tune from trifecta or someone else.

 

Already got the tune over the GM Stage 1 sensors. Bought the car last Saturday and tuned it yesterday. Big difference.

 

Thanks for the props Mike. When you get your new clutch and other mods on, let me know and we will make some adjustments...

 

Just wanted to put all these GMS1 posts at the top to see the ridiculousness.
