Hey has anyone done thier Intake Manifold by Raw Power. What do you think of it and has anyone noticed any power gains? The other question is, if you do the intake manifold do you have to bore out the throttle body? Or can you do one and do the other at a latter time? I don't know much about the Intake Manifold modification and was wondering if it is worth it and what excatly is done. Also I heard that you can bore the throttle body 65mm or 66.5mm, what's the difference.
