Hey forums,

I live in AZ, we have pretty poor fuel to choose from out here. Highest pump gas is 91oct, sometimes you can find 100oct. I want to start running E40 as I got the TU Pump for my F22 240. I’ve been considering buying the MHD Flex Fuel kit for the convenience factor, but if I remember right I seen a Kern417 video where he mentioned the kit doesn’t read 91 Oct. Is that still true? Would I just limited to Stage 2, and not stage 2+ because I can’t mix the E85 with 93?

Also, if I were to throw 100oct in the car, would the MHD Stage 2+ 95oct OTS tune be safe for the fuel I am running?
