Hey everyone, just wondering who makes the cheapest adjustable fuel pressure regulator, and what everybody thinks of the different brands. Thanks!

 

Why do you need one? The PCM will adjust injector pulsewidth shortly after you modify the pressure, so any changes will be negated.

 

There are legit reasons to adjust FP that will not be adjusted away by the PCM. I wrote up a huge piece about a week ago if you want to dig it up and read it.

I just ordered an AFPR (Racetronix fuel pump upped pressure to 46psi) - I went with the Aeromotive AFPR. It is $140, but I had bad luck with a cheaper one a couple years ago. Thought I'd just buy the best piece that will even work in a blown environment (ups FP based on positive manifold pressure, AKA, boost).

Even on a stock car?

 

Get whats called the "Hat Kit" from TPIS for 50$

 

I'd say it is not useful on a stock car unless you use WOT blocker, then you could lean out WOT without the PCM interfering. Not the right way to do it especially if you are ABLE to use WOT blocker in the FIRST place. LOL

In that respect, you are correct. But, who's stock?

bad96firechikin (the original poster) is.

 

Look at his sig again.

Look at his sig one more time...

'96 Trans Am, Stock as a block; 17X9.5 GMMG ARE 200S Wheels; MAC Progressive Rate Lowering Springs

The 355 is in the process.

 

I've been using the Metco AFPR. You just take apart the stocker and add the parts to make it adjustable. Pretty simple and works great. I think it was around $65.

 

Yes, but how do you know it's not for the new motor!?

How do you know it is?



Enough of that...lol

 

The cheapest is home-made. You can find it at Projecttransam.

 

Actually I was askin' fer the new motor. At the moment there is no motor It's been parked since November.

 

You may now call me stupid.
