I just picked up my car from the dealer. I had the stage 2 and GMPP exhaust installed. I love it. It's like a different car. It has a lot more power than I thought it was going to have. It's worth it. I can't wait for my Injen intake, 2.8 pulley, and my ngk spark plugs to come on thursday. Hopfully there will be a difference when I install those parts. What should I gap the plugs at? They are one step colder.

 

hey there congratulations! I'm gonna do the same thing..... where did you get it done (whidch dealer)?
and how much did they charge for the individual parts and the labor?
trying to get an idea as to what prices are out there are local dealers!

I bet it's fast
BTW how does the GMPP exhaust sound?

 

stocks .042 right? go down about .004 and if it runs fine don't bother with trying to get more gap, more just means you'll have to regap them sooner and it's honestly not worth running on the edge for a DD. Esp if your gonna keep teh same plugs in for a while. It'll suck ass to have to regap them just because it went over 70* outside.
