YOU with Fuel Pressure Regulators?????

[drakesdad]

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.

Davin, thanks for the catch, I changed it. I'm a idiot.....looking at way too many acronyms today........stupid is as stupid does Run Forest, Run

looking at way too many acronyms today

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

Why does this pertain to only AFR headed cars..hahahahah

 

[mytight95]

i've got mine at 38#, but i don't really think it is high enough still trying it out..

I drove mine in the post snow, wet pavement climant tonight just because I could not stand it and when I was in Mcdonald's drive through it just seemed to be rich.......but then again I need some custom tuning...lol

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.

 

[drakesdad]

So you guys think I'm safe at 39 with 24's?

I changed the thread title.

Mine is at 38psi. My fuel settings are done through my PMS.

 

[drakesdad]

Thanks Joe, I tried when I changed the comments in the thread but I must not possess your omnipotent power......

39psi, I tune with a Tweecer r/t.
