Just got the swap done and have one problem that is bugging me. Motor is 97 C5 and has CTR intake cam, skunk2 gears and ecu, aem filter, b/m fuel regi(which was set to 57 psi). First the problem, when in vtec the motor is fine until coming out where it bogs down until 4k rpms. It seems to fix and goes back to normal, the motor also pops. I have adjusted the fuel pressure down to 40 psi but it still happens. Replaced plugs with ngk iridium, msd wires and stock cap for now. What is happening?

 

Problem fixed, it was the exhaust cam timing was a little off. Running good now
