Well I have the bins from 20 kpa to 50 kpa, and from 600 rpm to 1200 rpm, all at the same VE percentage...so it can't be that. I'm really thinking it's the Delphi's, since Doug's findings have sort of proved it. I'm more thinking that the injector's electrical characteristics, and how the pintle is actually injecting fuel, is changing with the heating of the injector coil. They do seem to like more PWM though, as I can get it to lean out at idle by lowering the PWM threshold time(which gives less full open current, and more PWM current). I wish I had the money to get different injectors
