Car Wont Rev Past 3000 Rpms

#1
Hey guys, My car revs fine in park and neutral. However when you put it in drive it wont go past 3000 rpms with little boost, maybe 5 psi if im lucky. It also idles a little rough. It has an old Kenny bell 210/210 cam if that helps. Any ideas? Im at a loss.

Did your intake hose to the throttle body come loose? That happened to me, before I removed the crankcase vent oil return to the intake just upstream of the turbo.

Does it still have a catalytic converter? A plugged / partially plugged converter can make a car behave this way. A collapsed muffler will do it too.

Hey guys. The intake hose is fine and there is no cat. I just replaced the ignition module but haven't taken it out since it was installed. I will update you all asap.
