unless u really need the power gain...dont get it. If it wasnt for the fact i had so much back presure and loosing alot of hp cuz of the restriction i would have stayed stock. Thing is way to loud. iiunno about everyone else but hate all types of exhaust on cobalts or any 4 banger. thing is so loud and i feel like a retard. I was always saying "oh look at the retard with a loud exhaust...waste of money to make yourself sound like pos." And now i feel like a pos cuz of the sound....but when i step on the gas and get the power...it makes me feel better. lol

Your tune is for stock exhaust.
You've opened it up a TON.
I'm sure your trims are probably out and you've likely moved to different areas of your fuel/timing maps.
That's sure to throw your mileage off

Small update. Steve adjusted my tune again. The trim was at 25% so i was using alot of fuel..lol. We put my afr back to 11.9. Added 1* of timing so im at 25* of timing...no knock. After 3 or 4 pulls on the highway the highest we seen the iat2 get to was 149*...also it was 27*C outside so that played abit in the temp. He also found a issue from my old tune. Idle issue is fixed. Also changed the amount of boost in 1st gear. From idle to 4000rpm its 75% and then works it way up from there, at 5000rpm its at 100% boost. Did a pull from like 5kmh...tires didnt break loose at 60% throttle. Did another one and it broke loose at 68% throttle. Car feels alot better now. Thanks again steve! Cant wait to dyno and go back to the track.

Before i put the tvs on i ran a 14.4@106 with my m62 - 2.8", 60lb injectors, meth, h/e and cai...had a completly fucked up tune with that. I have to learn all over how the car launches now at the track but if i can get my 60' down low i should be able to get to 12.9 or 13.2 ET @ 110-111mph

yea thats what i heard .5 or if u r good 1.0 with slicks. When i come back from the field with the army and i get to the track, depending how many passes i get that night iiunno what i will make for time. Like i said the car launches alot different now. So i have to learn how to launch it all over again. Letting the clutch out is the same but the amount of gas is ALOT different. When i was at the strip on friday i would stage at 2000...ease the clutch out, once fully out i would floor it and not spin....remember i was only at 40% boost in 1st. Now today when i did a few pulls while we were tuning we turned the boost to 75% and at 4000rpm it starts to climb...by 5000rpm its at 100%. I did a launch on the highway was only at 60% throttle...tires didnt break loose and the amount of power felt exactly as i did at the track when i floored it. Then i tried again...computer said i was at 68% throttle and tires broke loose.
