so i have been throwing parts at my car for a few weeks now trying to correct my fuel trims.
my idle trim is between -1.5 & -2.1
my partial trim is between +16 & +21, which is forcing the ecu to cut boost back.
i have been on APR's stage 2+ for over 110000kms.
vehicle mileage is almost 185000kms.
i've replaced pcv, maf, valve cover, and O2.
i've even bypassed the pcv from the intake manifold, to rule a heavy leak into the crankcase.
i've ran the car with the maf disconnect to rule out the aftermarket intake.
looking for more ideas to diagnose this issue.
