    What psi do you have your FPR set at? I set mine at 39. Just seeing what others are running at...

    Been there, done that. I think I'm at about 45# through 30# injectors but I'm still fine tuning at the moment.:nice:

    IMO.... fuel pressure regulators are not worth the money in our vehicles. The stock computer will eventually regulate it down to the equivalent of 39#s anyway. Instead of bumping fuel pressure, get bigger injectors and tune that way, leaving the fuel pressure at 39 PSI.

    I had mine at 42 with 24# injectors. At idle it was rich. But on the dyno it was right where it should be.

    I forgot who on here told me that if I was around 38 or 39 I would be in the ball park. I am running 24's and have to put in the 255 fuel pump and then the decision is.....custom tune/chip or tweecer. I have been reading up on some of the tweecer info and they sell for 580.00 give or take.....I have a lap top I bought for something like this but I have to admit I am a little leary of messing something up.......:shrug:

    I have mine set to like 41-42 psi. I used to run at 45 and wideband at dyno said I was starting at about 13.5 and at 6k it worked all the way down to 12.5 so I figured I could drop it a bit. THis is on 24 lb. injectors.
