Why would running the Aux system on E85 drain the LPFP to the point of running lean, while making XXX Whp, while the MPFI setup wouldn't run the LPFP to the pump of dropping rail pressure and running lean?
360whp of fuel, is 360whp of fuel. And maybe their is the difference... Maybe the AUX system car makes 400whp, and 100% E85 is too much to ask of the LPFP, while the car with 360whp has the mpfi and the LPFP CAN KEEP UP with 360whp.
So... If the AUX car turned it boost down by 40whp worth, it would prob be able to handle E85 just fine. And the backwards is true as well, if the MPFI car turned the power up from 360whp to 400whp, then the same LPFP would be the limiter.
Or am I not getting what is happening ?
