ethanol

  1. Q50 General Discussion Forum
    Just want to know what u guys are running for gas on the daily. I always run on 93, its a little expensive but its worth the performance. Ive seen people run ethanol with the flex fuel kit but i dont know if ethanol is good for daily use or just for racing nights.

    With FBO + tune what is the max E% you can run on the stock fuel system, what about with just LPFP? after doing every bolt on i want to run E30-40 with flex fuel. But would prefer to avoid HPFP if possible. AMS said need HPFP and LPFP but I believe they where talking for E85.
