Will switching over to E85 effect the HPFP much. After afriend did the conversion with basic boltons, CAI,LTH ,his HP is really realy low and his injector PW is around 3.5ms at idle. His low pressure is fine.
Is this normal??
Thanks!

Need a log of lift and DI pressure and the tune.
That is not normal
Didn't think so. Never tuned a Gen V for E85 so I was not sure if it had any bearing in regards to thr HPFP or how the DI pressures might act.If thats not the case, im thinking the HPFP took a dump out of coincidence.

The DI pressures shouldn't change like that just by going to E85. Technically, enabling the sensor, the DTC and changing the stoich scale would be enough to get have it adjust for the fuel volume properly. But even on full E85 the idle pulsewidth would be a lot closer to 1ms.
E85 wouldn't have caused that alone. I suspect the high side pressure is low for some reason.
A log would help know for sure.
