So here in the bay area we just started receiving E85 at our pumps. Holy crap this is great fuel for boosted cars. Take a look at the difference between using the two fuels 91 vs E85. I don't think I'm ever going back to 91 now. My scanner isn't hooked up, so I had to take pictures of the dyno graphs. On 91 it made 262whp/259wtq @ 23psi on E85 it made 333whp/318wtq @ 27psi +71whp/+59wtq Mods: 2005 Evo GSR TBE no cat RC 1000cc injectors Walboro fuel pump GM 3 port The car is an animal now. I don't think I'll ever got back to 91 unless I'm forced to.
