If anyone has any input, I could use it because I'm really at a loss. My 99 Cobra with paxton novi 1000 was putting 422hp to the wheels with about 6psi and the fuel pump at its limit. I wanted more so I installed a paxton air/air intercooler, focus rally pump and smaller pulley. Now I have about 10-11psi. Its getting plenty of fuel according to my air/fuel on the dyno. We rolled it onto the dyno and it baselined at 450rwhp. It went down hill from there. Now I can only manage at most 433rwhp with the new setup. I have no idea why but the power just isn't there on top end like it should be. Anyone been at this crossroads before?
