340/E85/D1SC/FItech1200 big hp SB guys step inside please!

sub com, thanks for the tuning tips! When you say switch to pump gas initially for low boost, are you suggesting this because it would ease the burden on the fuel system or because the Fitech wasn't working well with the E85?

I probably CAN run pump gas through this thing if I keep the boost low, I just really liked the idea of E85 partially because of the cost but mainly because I wouldn't have to worry about detonation nearly as much and it should keep the engine cooler in the summer. Things I don't like about E85 is its tendency to gum up/absorb moisture when sitting and the octane variances at the pump. A tuner I know said that with only 12-13 PSI, even filling up with the worst pump E85 shouldn't give me any problems with detonation and the FItech would adjust for the ethanol content through the AFR's. I may try to make a low boost tune for pump gas for the sole purpose of running during the winter months when I don't drive the car as often, to avoid the E85 from clogging injectors and what not.
