I can… but at that point why not do a pump and race gas tune? C16 is a much higher octane than E85, that means moar powah!

I cant baby around in my car like a grandpa. I don’t drive it much, but when I do, I put the hammer down. I get about 14 city / 27 highway on pump. I have to do a pump that will move more volume, -8 Feed, -6 Return, new FPR, and fuel rail. Current fuel system with bigger injectors will support 600whp. If I run E85 with my current fueling, I will make less power than I can on pump.
