I have a gsr with the following mods.....
Intake, header, exhaust, Crankshaft pulley, Type R cams, Cam gears, ECU XS/Mugen chip, with ignition timing set at 16 degrees, cam gears intake adv 1degree and exhaust retarded 2.5. My question is what should my fuel pressure be set at with the above setup. I have heard many different number but my car right now seems to be running rich. Also tell me the numbers w/vacume line hooked up and with vacume line off. Please this is very important. Also any suggestions for camgear setting and or ignition timing would be appreciated!!!

Thanks

 

you measure FP with the vacuum line off and pinched.

there is no sure way to tell without taking your car to the dyno, and have them do some runs for FPR only.

your plugs will tell you a little (black = rich, white = lean, brown = perfect).

 

got to get a dyno done to really get it right.
