    I just installed an Aeromotive adjustable fuel pressure regulator on my 98 Cobra. (Adjustable up to 70 psi) I run a 125 shot Zex dry kit at the track. Now, I still have the stock 24 lb. injectors and stock fuel pump.

    Do I need to bump my fuel pressure up when using the juice? Or will the Zex box do all that automatically? I plan on getting my car tuned soon, but I just wanted to know what I should do for now. I am trying to dip into the 11's and I wanted to know if messing with the fuel pressure would help me or not. Thanks!!!:shrug:
