0% PI tables work fine showing Pi only at idle, sometimes, 100% DI cures every single problem I have ever had with fueling. Problems I have tried to fix with AVCS tuning. I hate PI now. It's louder, less economical, and accelerates worse than DI. I'm trying to work with AVCS timing now to get the Intake Late/Exhaust Late internal EGR working correctly. I'm not sure if I can do it with DI alone, or if I need PI to get it to work correctly. I'm just concentrating on the area from .3-.5 load, and from 1200-2000 rpms. That should boost my highway mileage.
