Remote tuning a customers car. In beginning stages of dialing it in and the SD table is looking all kinds of weird but fuel is hitting its targets perfectly and it trims in really nice. Details FP3065, E85, Walbro 450, FIC2150, your basic "built motor" list. Car made 551hp at 25psi but im hesitant to keep going with this car because how the SD table looks. Generally I look for 100 on the SD table at peak torque then go from there. Currently it suggests an air flow issue at peak torque then VE goes up possibly suggesting a fuel pressure issue that we are waiting on a sensor to log it to verify. Boost leak tested perfectly, tried new wideband sensor, pulled piping out to look for a rag or some sort or restriction in airflow, changed intakes (intake is a hard pipe with another new filter). Around 10psi thats where i see the numbers start to fall off. Looking for suggestions what others think it could be. Ive covered everything I can think of minus logging fuel pressure
