[QUOTE="L8APEX, post: 16595076, member: 51947"] Upgraded injectors and a dual pump/ return style system as E85 runs really rich, usually under 10:1. I wouldn't trust a boost a pump with forced induction. I'm running basically a GT500 dual pump system, id 1050's and have a turbo so I [i]really [/i]dont want to go lean and pop my engine. Most of the fuel systems in newer cars are fine with alcohol though, as it's been used as the primary octane booster the past ~15 years after getting rid of touline. (most Fuel is E10) Most tuners can give you a flex fuel tune that uses the 02 sensors to sniff the amount of alcohol in the system anytime after you add >3-4 gallons. I dont have one, I just run it down and if I still have several gallons of 91 I'll fill up with E98, or just get it to about a gallon and switch then. Now that I'm daily driving the mustang I'm thinking of going ahead and getting one. With a return style system you can get a line and hook it up to the rail and get a fuel pump tune that you can use to empty the tank fairly quick. I have one but I don't use it as I have the cover on my engine and can't access the rails without taking it and the strut tower brace off. [/QUOTE]
