i know stock fuel pressure is about 43 psi. right now i run about 47-48 at idle. my fpr is an aeromotive that refereces boost and suposedly raises pressure on a 1:1 ratio. i run about 20 psi so i guess i run around 67 psi fuel pressure under full load. what do most of the tuners run in fuel pressure under full boost? what do they have it set at idle? would i gain any benefit from raising it a tad?

 

47-48 with the hose on or off? With the hose on that is a lot for base fuel pressure. What injectors do you have? Depending on your setup you really should not need more than stock base fuel pressure. The Aeromotive is a 1:1 ratio FPR.

 

47 is way to high at idle. it should be 43 or so and that is at 0 not vacuum.

 

it is 47 or so with vacuume hose on. i have 880cc TMS injectors, perrin rail, braided -6 lines, 255 pump. if its too much what should i put idle fuel pressure to with the hose on? what kind of fuel pressure should i run on boost?

way too high, it shoudl be liek 39 or less at idle. Oh lower it, and retune the car. To much fuel, especially at idle, will make the car run rough and fowl the plugs.
