I have a b18c-R in my da and am having fuel delivery issues. it has a Jun head and stage 3 cams and gtr injectors. my tuner can not put anymore fuel in without the car throwing a check engine light. it has greedy e-manage blue. we are thinking that the stock fuel pump and pressure regulator are not up to the job.
I would like some thoughts or setup info from you guys that have the b18c in your da9.
