Question Can I get some more power from the fuel?

Im running a stock 93 block with hyperpathetic pistons , Gt-40 heads, GT-40 Intake (Fully ported) 65mm TB, Pro-M 77mm, w/Granitelli meter, Nitrous Cam, 125 Shot of juice, 255 lph intake pump, Kirban adjustable regulator, and 24lbs injectors. Right now the regulators@ 38Psi w/ vac. off My question is there more power/tenths to be made from the regulator? If so whats safe with the juice...........also im running free flow exuast basically longtubes with no pipe or mufflers? I think it's helping but could I be losing valuable back pressure?

If I am following you, you are running 125 shot, and your fuel pressure is at the stock setting of 38psi.
The only reall way to find the right setting is to get a few dyno sessions going and get your A/F ratio at different levels and see what performs best. I would bump it to about 40. you <b>really</b> don't want to lean out any. Are you running a wet or dry system? If you are running a dry system, you are letting the MAF do all the calculations, right?

In other words you're spraying through the MAF. I hope this helps some. What kit are you running? Anyway, talk to you later.

I'm running the dry ZEX kit..temporarly....till I get the new motor then will move up.anyways it's the 125 dry kit from zex......But are you saying that it does'nt matter what setting I put and that the computer (which is stock) will put it's preset amount anyways?
