my setup is a stock 98 GSR, obd1 p72 & hondata s200 w/ a basetune, 60 trim garrett t3/t4, 450cc DSM injectors, B&M fuel pressure regulator, n a walbro 255lph fuel pump on 7.25lbs(.5bar) of boost
the car starts but idle's pretty rough. my fuel pressure gauge is reading 40 at idle, n im not about to go WOT on a basetune(but it should be about 47-48). i was told by an acura dealership that stock fuel pressure should be between like 48 to 54psi(that sounds high to me tho). well on my FPR its hard to even make it as high as it is now. where should it be at for my setup? and could a basetune + inpropper fuel pressure(assuming its off) be causing my rough idle?
