Power Package?
I just got my stock 2002 z28 a few weeks ago & had a magnaflow catback installed. I am very happy with it but would like a deeper sound & better performance (who doesnt?). Being that I am a novice to LS1's, what do you think I should do next? I've heard of a "Power Package" that includes a few different parts that will boost rhp up about 30. I dont plan on racing the car (maybe a little street) and also dont want to void my GM warranty. Is it a good idea to go with the Power Package next? I would appreciate any advice.
