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

Uh..do you mean FPR? (Fuel Pressure Regulator?) I think you do, just to clarify.

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

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.......

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.
