255 fuel pump-12:1 fmu-stock injectors running LEAN
aight its a gsr with a t3/t4
boosting about 8lbs with the stock injectors and 12:1 fmu and a high press intank.
it runs lean through the whole rpm range in every gear, havnt done a fuel pressure test but what do you think it could be?
would a ajustable fpr fix this

Re: 255 fuel pump-12:1 fmu-stock injectors running LEAN (lowboost civ)
fmus work better with inline fuel pumps vs intanks (correct me if im wrong) but i believe that's why kits include inlines vs intanks, because they increase the pressure just before the rail, or something liek that.
Switch it out to an inline pump and you should be ok - however i hate FMUs and for all you and i know that may just be your setup.
