Default Revs go up.. speedo don't.!!!

Anyone know what would cause my huge loss of power? The engine revs (slower than usual) and the car doesn't pick up speed hardly at all at WOT. It seems like it's trying really hard.. but isn't doing much. It's not throwing any codes but I know something is bigtime wrong. Sometimes it'll surge a little too. I pulled the plugs and they didn't look bad but I replaced them anyways along with the wires... no results. Anyone have an idea? Thanks in advance. I probably should add that it's cammed w/ longtubes and pretty much all the other boltons... nothing crazy.

do you happen to have a leak on the EGR hose? or a different vacuum leak? I had that problem and it was my EGR hose leaking at the intake manifold
