well i have a drag kit on my d16z6 with the 12:1 fmu and a inline pump and am running 5lbs. but i seem to be running lean my plugs are almost ghost white. anyone know what the problem could be. do you think it could be my fmu. if it is how do you check if it is good or bad.

 

I keep hereing about static fuel pressure causing lean conditions from 0 to 3psi of boost. Try raising your static fuel pressure a bit and see if it helps. Do you here any detonation? Did you retard/advance your timing? Do you have any hesitation or drivability problems? Need more to go on.

 

How long have you been running on the plugs?

 

i do not hear any detonation. my timing is retarded 2 degrees. my plugs are a week old and gapped to .32. i also have msd ignition.
