Yes - if you run E85 it will burn faster thus bringing the MPG number down - but if you run standard fuel in the E85 bio-tuned car it will be normal.

The E85 is a give and take - result is a wash really. You pay less for the fuel, but it burns faster - so in the end if you do the math - it's almost like getting high test performance for low test costs... makes any sense? It's biggest gain I see - cleaner burning and greener for the enviroment. Aside from that - unless you have a full built race application, it's just another fuel to pump and screw ppl and their cars up lol

I have the E85 Bio-Tune in our 9-5 and it runs nice on it - like a Stage 1.5 tune over the stock ECU. Plus you get the nice SID controls to monitor your engine data in swedish short hand...
