No difference? Well i just thru the cam in my sig into my car and after driving it and raping it numerous times i have come the conlcusion that i dont feel a difference....Anybody else feel like this after a cam swap? I know its not tuned but i think i should atleast feel something. Kinda dissapointed but i have no way of knowing the difference cause the track is closed and dont have the money for the dyno just yet.

Dont forget that increasing your engine's cam duration moves the power band up. Its a trade off. You lose a little down low as cylinder pressure bleeds off. But you gain a lot up top. My guess is that when you punch it, your probably somewhere in the 3K range where torque is right around where is was in the stock cam. Try bringing your rpms up a litttle higher to like 4 or 4.5K and then punch it. You should notice a difference up there.
To gain back your lost low end, you need some heads with bumped up compression. Also a tune to beef up the timing would help quite a bit.
