I need some info. I have a 95 gt that i just bought. it has headers, full exhaust and apparently some internal work done with an e 303 cam.Has a jms custom chip .also has an adj. fuel pressure reg. what would be a good psi setting for the regulator?thanks in advance
39 PSI is stock. I'm also willing to bet that the JMS chip was created with the stock fuel pressure as a parameter. I would tune your regulator to the stock setting, reset your computer, then fire her up. Should help chase away any problems you have... the e-cam is notoriously difficult with our EEC.
