If I weren't trying to sell my car, I'd definitely look into this. I'm assuming that the bump in compression from 2000 MY SVTs came from the heads, so my Hyrbid should be 11.5:1 compression in theory. If I need 30% more fuel, but my tune is already 11.2 AFR, all I'd really need to do is bump up the timing and add maybe a tiny bit of fuel. I've already got a 255 lph FSVT fuel pump and 42# Terminator injectors. Makes me wish that I had the PRP for my XCAL.
Negative... RBT and LBT (Rich and Lean Best Torque) points of E85 are different from gasoline.
You tell the computer that your injectors are 30% smaller than they are and tune to gasoline equivalint AFR's in the tables in the ECU. Or you can use lambda if that's an available option for you.
