I am running an lly and trying to get my truck tuned in and try to make some mileage 16 is my best so far. switched to the lbz intake setup with a GT4088 Turbo built motor, port polished, bigger valves, and 60 over injectors. i can get it to run great got great power and throttle response but if i dont turn the MAF DTC off i end up not having any power under 2000 rpm. Do I need to be playing with my MAF Flow rate or my MAF expected Airflow?
