Message	has anyone developed the electronics to use a standard flex fuel alcohol sensor to infinitely vary the tune between a 91 octane tune and an E-85 tune? I read where Cobb Tuning is getting about 600whp out of a stock turbo GTR. Because of the stoichiometric ratio, you should get more energy out of a pound of air. There is a post on the North America Subaru Impreza Owners Club site that goes thru the calcualtions and E-85 gives you potentually 127% more energy per pound of air. A stock turbo Z32 could get close to 500whp. That is with better cylinder cooling by using 30% more fuel, and better exhaust temps and radiator temps due to the E-85 burning a lot cooler.
