guys, i have a question...both comptech and AEM has fuel pressure regulators. which one would you guys buy? thanks

 

AEM or a different brand. You going SC or Turbo? I had one with my turbo kit before, but the name of the brand escapes me. It came with the Drag 2 kit.

 

If it came with the drag kit it was probably the vortech.

 

i have the nos fpr................they dont make a difference on our cars

 

Why is that mchtypes??? Would the FPR help since I am running a nitrous system? Or do FPR's just not work correctly with our cars?

 

I dont know about the TL models, but the S models run rich as is. Some people leaned out the top end for more power. Do you have pics of your ride? How is that exhaust?

I can also attest that the FPR is completely not necessary for our cars...
our fuel system runs at like 97% straight from the factory no FPR is going to improve upon that...
for those with V-AFC's like me the only thing we really used them to change was to lean out the top end so an FPR is not necessary unless you have a secret Forced Induction project going

 

I'd have to agree with Astro here.Fuel injection systems are called closed loop and in effect any attempt made to add fuel will be countered by the ecu that runs the show.So simply increasing the fuel pressure will be dialed out by the ecu since it can tell from the oxygen sensors what is going on.It will simply cut back the injector on time to compensate for what it sees as a rich mixture.Jens

 

Alright, so I'm ruling an FPR off the things to buy list . In regards to the Magnaflow exhaust, It sounds awesome, identical to the comptech exhaust. Except mine in particular is a bit louder because I had a straight pipe installed in place of the existing resonator/pre-muffler. Also my exhaust is a quad tip.

 

do you have pics?

yeah, pix please!
