hey guys,

i know every car and engine runs slightly different, but could anyone give me their air map for an RB20det on an SAFCII so i can compare it with mine.

mods = fmic (small), 255lph walbro, boost @ 12psi nothing crazy.

reason is because up top im feeling a little bit of studder, and im just wondering how i should adjust my safc, add air or decrease air. im thinking decrease air, but just wanted to see how other people have their setup.

thanks,

gamay

you have no need for a SAFC with those few modifications. playing with your airflow might make it run better, but only mask the true problem.

i would check your plugs, coil packs and timing.
