i just installed a B&M fuel pressure regulator and gauge . we installed the gauge first and it showed it was at 34 psi stock . is that about right with a b16 sir II ????

my mods are : aem intake , comptech header, catback exhaust, skunk2 intake manifold . im also running a ITR ECU . what should i set the psi on the regulator at ?
like i said before , it showed 34 psi at stock setting before we did the B&M fuel pressure regulator . thanks in advance .

 

should be fine, stock i thought is around 38psi i believe?

 

well actually my question is : what should i set my psi at with the B&M FPR ?

 

just getting ready to do my fpr too. stock according to haynes (yea, i know, should be using helms) is 30-38 with vacuum attached and 40-48 w/o. i've read to start at 40 w/ vacuum attached if you just have bolt-ons and adjust down from there. i've also read that a couple people ran 40 and thought it was too high, so they knocked it down to like 37 and ran much better. let me know how yours goes and what you set it to. thanks.

 

you're suppose to set it with the hose off to simulate WOT

 

so set it at like 48 with the hose off would be good?

 

???

 

set it around 38, leave it stock until someone that knows what thier doing tunes it

 

with intake header and exhaust he should add a little more fuel you can try 48.. check your plugs after a couple of miles and of course famous butt dyno always works .. if you have a cat i dont suggest too rich..

 

yeah i also think i should wait till an experience tuner tunes it , along with other parts . we set it at 36 psi . originaly it was set at 34psi . wich i think either or is preatty low but i just dont wanna mess something up . thanks

 

my opinion, haynes says stock can range from 30-38 with vacuum and 40-48 without, so i'm gonna set mine at 37-38 with vacuum and 47-48 without. and personally i think its stupid to pay someone to dyno-tune your car to adjust an FPR.

 

are u guys doingthis with the key on the on position or at idle

im a curious

At idle with vacuum off.
