Hey guys/gals,names Joe and i just purchased a Red 05 SS/SC(heard its the fastest color lol)..was a srt4 owner and switched to a cobalt after many family problems,so got rid of that and got this whip...im 20yrs old and live in skokie which is just north of chicago..if anyone has questions feel free to ask..


Well guys i bought my cobalt on feb 8 07 and i have a buddy that works in a shop and can dyno tune my cobalt on the dyno for 120 bux 3 runs with tune...how much of a diffrence will i c if i get a tune WHEN i get the GM S2 package..

 

Get a before and after dyno.

i'm curious about that 40 hp gain.

 

I guess a Welcome could be in order as well, seeing as this is your first post. The gains will vary on who's doing the tuning. I would think anywhere from 10-25 extra ponies. Make sure that they give you a mild tune to compensate for temp. drops in the weather. You don't want them to lean out your car too much then have the weather temps drop like 10 degrees. That'll blow the motor for sure..Keep us posted on the numbers though man..Good luck
