I just got my motor built and turbo installed. I have crower cams, 8:5:1 compression pistons, t3/t4 turbo, fuel pressure regulator and high flow fuel rail,walboro 255 fuel pump . I need to get it to the dyno. Would it be ok to drive if i just bumped the fuel pressure with the fuel mods i have now or would it lean out still?

 

pull out ur spark plugs and look if they're black (rich) or white (lean) at the bottom....... how much you boosting ??? 5-7 should be okay with all u got....

 

i just put the spark plugs in, haven't even run it since then. they are the bkr7es-11's(2 step colder i think?). Also it would be at 7psi
