E30-e85 fuel

[Jtc527]

Was wondering if anyone has run into issues with fuel systems running more than e30 in your car.

Very common. I think every Stinger owner figures that out at some point. HPFP will crash

Only seen hpfp crap out? Are there upgraded ones or just replacing with factory again?

Yes there are upgrades. Spool makes two, fx-150 and fx-180. With an upgraded pump you can push E40-E45. Ive heard of some hitting 50 if the weather was warm.

What fuel do you use if you don’t mind.

My car loves between E27 and E30. I have an upgraded pump and I've run over E40 but saw no performance gains. I do have the fx-150 and the fuel-it sensor.
At the track I even dilute my race gas with E-85 to bring the E content from 0 to E27, the car loves it.
