I was probably one of the first to install the Comp Cams in my 5.0. It produced about 35-40 additional hp per the dyno compared to other non cam similar equipped 5.0's. I was hoping for some cam lope but it's just not there. we had an extremely difficult time getting the tune and idle set properly. Back to stock cams. My tuner told me not to install the Comp's but I didn't listen. It's just money, right?
Well that sucks to hear, those things aint cheap. I just put in a Pypes X, that along with my Magnaflow axle-backs, and the little sound difference with my Airaid MIT, I'm happy with the sound. If I listen hard enough it almost sounds lopey at idle with my ear in the exhaust tip. If I'm imagining it who cares if others can't hear it, I do
I've given up on the cams, I love my low end power and with a gear swap, currently have 3.15s I'm sure I'll be even happier. If I need a cam sound to make me sleep good at night I'll just fire up my 08.
