E85 or No E85
After seeing multiple E85 thread pop up and a onCue gas station (they carry E85) going in down the street from me, I am thinking about E85.
Come May I am doing a cam and re-tune. I will also have the A&A Fuel System installed by then (with KB boost-a-pump if need). The car has a V3 Si with a 3.8 pulley and methanol injection.
Question is, should I go E85? What type of benefits will I see power and reliability wise? Is it possible to tune for E85 and 91? During my reading I saw that 2004 models have the ability to add a sensor to the gas tank to detect what type of fuel is being used. This would allow for the car to swap timing and fuel tables on the fly correct? This would be a major plus if I got in a spot where I needed to run 91/93 without going full throttle.
Maybe I am crazy...

12-14 mpg avg if im in 6th at 1500 rpms. Fun afternoon drives hammering hard I go through a tank in an hour easy.
Would never go back to anything other than E85 though. With E85 on a 105 degree day the engine and cooling system still thinks its 50 degrees out.

I'll probably be using E85 for my high-boost tune up. I see no reason not to since there is a station 10min from my house. I do have a 30gal Gas Caddy that I will use to store it in. On the flip side, I have no reason to use it as a daily fuel.

You can refuel with non E85 on same tune and drive on that till you find E85 if need be and it wont hurt anything and will run just fine.
