Hey guys as you know i just put in my new fuel pump (walbro 255) and new injectors (pte 550cc) and my new bov from mitsubishi.... I also put in a universal megan racing fpr. I know that the stock fuel pressure on my 98 gst is about 41 psi... what should I set the new psi at? Why is my fuel pump extremely loud? And when I hit the gas hard it pretty jumps off the ground. Whenever runnning it for a little while it pretty much messes up the idle and stalls. any help will be appreciated. By the way I will have my safc in about 2 weeks.

 

well alot of the problems your having is the injectors. You really need to tune thos otherwise youll get what your getting. And for the fule pressure just set it to the stock idle pressure. So if your a 1g then set the FPR to around 27 psi and if its a 2g then set the idle pressure to around 35 psi
