ZL7 Performance???

These are just my opinions but,
SLP headers- way overpriced
Loudmouth exhaust - decent
Air Filter setup - decent
SLP MAF - waste of money - no power gain
Diablo programmer - waste of money - minimal power gain
SLP rocker arms - waste of money - no power gain
SLP valve springs - what for ??? -no power gain.
My guess, if you bought that package, you are looking at 30-40 RWHP gain at best.
