Corsa's not for the HP...it's for the sound. I'm good with stock pipe music
I was looking at the cams...the have like three different ones for the 6.1, and no explanation of the differences. Help?
I also think the heads should make adjusting the redline and shift point a bit safer? I'd think the valves'd stand up to higher RPMs faster than the stockers...
Well, if just the diablo'll get me in the neighborhood of 400, I'm looking at almost five grand for an additional 20-30? That doesn't sound right. Diablo, Heads, TB, intake, and AFE should yield more than 420...I'd be looking for more like 450 for that kind of investment

Maybe I'll just stick to the Diablo.
