I'm just curious what kind of hp and tourqe #s I should be getting. I've been wanting to take to the track to see what it can do. Also. Every now often my check engine light will turn on then it will just turn off should I be worried. I don't hot rod my truck so I was just curious to y it's turning on.

At the 5psi, you should see an increase of about 40% in HP and TQ over stock at the flywheel. As for the check engine light, is it the factory light or the little amber dash light that is hooked to the Whipple system?
