It isn't designed for a high performance engine. Every vehicle that is a flex-fuel vehicle has a terrible VE and low RPM redline and so it works fine. If you were to tune for E85 today, the tune could potentially vary by upto 20% during the next fillup.

E85 was a loop hole for the domestic manufacturers to gain CAFE standards since they only measure MPG of gasoline and that is 15% of E85 that is measured. So a 1/2 ton Silverado gave tham 91 MPG!!

IMO, methanol is a lot better alcohol. Meth has atleast 20 higher BTU consumption compared to ethanol when vaporized. Its specific output is also greater and it is more consistent. Meth costs more than E85 but is the same as E100.

Either ways, you can't use it for direct injection. E100 or M100 would require a lot larger fuel injectors. Gasoline is not conductive but alcohol is and so it may not be uasble in the direct injectors or possibly even the port injectors. I think the only way to make it work would be a new cast/fabbed intake plenum in place of the OEM thermoplastic plenum and a couple of injectors in the intake track right after the throttle body. This way you could still keep the OEM fuel system intact and have it work as designed. Additional fuel could be then administered from the additional fuel injector(s).
