I've heard different things on how much horse power and torque you will gain from doing upper and lower intake, throttle body, and CAI. I have a Edelbrock Performer RPM 2 intake, 70mm throttle body and a BBK fender mount CAI. What is the usual gains?

Anyone???

You will be dissapointed until you do heads. Right now heads are the bottleneck. Once you get new heads the intake manifold becomes the bottleneck. Wait and do it all

+1 on heads. i would guess maybe 15-20 rwhp on stock heads.

with stock heads hardly ne... mayb 15rwhp.... get the better heads if u get heads ull probably see anotehr 40rwhp if u have the rite cam for you set up... so like 50-70rwhp for a h/c/i that matches up well... think about it... a cobra has 25 more hp than a gt and thats a very mild h/c/i upgrade... like near no different... so a nice h/c/i on a gt could show 50rwhp easy

Not going to see much with stock heads.
