Product: AEM ADJUSTABLE FUEL PRESSURE REGULATOR

Price:214.00 for me

Review:This product even though its not necessary has made my car able to have more or less gas put into the fuel rail by limiting or allowing more psi to travel through it. I am able to get the full potiential out of my injectors. My plan from the beginning has been upgrading fuel and air capacity and this product is just one of many mods to my car improving air and fuel flow. I recommend it to anyone with a aftermarket fuel rail!

what psi have you set it at?

Honestly without forced induction youre not going to see gains by adjusting fuel pressure. Youll just be spitting unburnt fuel out the exhaust and getting horrible gas mileage.

I have it at 45psi and pete its only 5 psi more than stock which is 40psi. I dont have a turbo but I do I can go larger than I could stock but anyways I'm going to do internals and the head gasket just this cheap stuff first.

i believe this thread is supposed to be in the 6th gen review section
