Just got my new GN last weekend. I was told that it is running rich and that the fuel pressure may need to be turned down. The exhaust fumes are really bad. Here are a list of the mods:
Craig Te-67 turbo (running 19 lbs boost)
Action Fabrication 15 row stock location intercooler w/electric fan
Translator and 3.5 MAF
62 mm jay jackson tb & upper
Moroso underdrive pulleys
4" ram air
200 R4 tans. built by Rosler w/ manual valve body
3.42 gears
Stock cam
Stock heads
Vigilate converter (4000 stall)
Mosler axles
TA girdle cover
BMR upper contole arms
Box steel lowers
Air bag on pass. side
MSD 50# inj. w/ Lubrant street chip
3" S.S. Houston D/P
3" ATR S.S. single shot (going to dual 2 3/4" dual stainless system from gbodyparts)
93 oct fuel
I just installed a rail mounted fuel pressure gauge today. It measured 55psi w/o vacuum and 47psi w/ vaccum. What Fuel Pressure should I be running?
