Ian from Bend Calibration is helping me tune a max effort map on E50 and so far the car loves it. I tried E60 and the pump was showing signs of pressure loss. So we went back to E50 for now. Before meth.
And yes I've head there is a work around that some tuners use to run full E85 by lowering load limits etc. But, the true limit of the fuel system is E60.

True Limit of the fuel system is E60 on stock turbos? |
The hpfp starts crashing after e60.
It's not dependent on hardware it's the ethanol content and limitations of the factory fuel system. |
Papa,
Do you know where in the RPM band the stock HPFPs become unable to provide enough fuel when using E85? I would like to run E85 without mixing and stay in the powerband. The only issue I've heard of is topping out of fuel supply so just don't rev too high when racing.

Hey Tommy,
Well on my car it was around 6k rpm. But, I'm in the middle of the tuning process using ecutek flex fuel. So, that may be different for you my friend.
I've heard the bm3 tuners can lower load limits to get higher ethanol content without pumps crashing.
