Hey guys! I need your help! I have a 88 CRX Dx with a Si head thats boosting 5psi. My car was running fine till I installed a Skunk2 manifold. Everytime I try to floor it, at a certain rpm (5000) it starts bogging out. But when i dont floor it (half throttle) pass 5000 rpm, it doesnt bog. Is my fuel pressure?? It is set at 40psi and I have a vortech 8:1 fmu! Do i need more gas?? Do I retard the timing?? (timing is 2 degees advanced right now cause it was running better this way with stock manifold). What should I do?? P.S. My air fuel gauge reads on the rich side when I floor it! Thanks for all your help!
