I installed a Cobra Intake in my sons '89 GT. Everything went smoothly so I thought. Finished the swap, changed the oil, set the timing at 12 deg. Today I took it out for a test drive and it seems that the friggin car has half the power now that it had with the stock intake!!!!Is there something that I overlooked or something im missing. I'm *old skool* all this EFI stuff is new to me, I thought I would give it a try but I'm this close to converting this thing to carb like my '92...Any suggestions?
