You will be limited to about 30-35% without the backend flash as your trims will quickly max out with the adjusted fuel scalar the flash provides. The max blend after flashing will be determined by the strength of your HPFP and how much boost you are running. The only way to do determine this is log. I'd recommend starting with low mixes, log, and work your way up.

Can we run straight 100% e85 with a stage 2 fuel pump with stock turbos? So somewhere at the 450-500whp level

I think u need port injection in addition to the upgraded lpfp to run 100% e85. I might be wrong though.

The majority of cars can't. The Stage 2 pump is capable but it basically comes down to how the HPFP responds and just what the strength of your E85 is. Most HPFPs can't keep up at the boost levels required to make that power.

Port injection would solve the problem but also keep a look out for Fuel-Its throttle body port injection kit which should be perfect for that HP range and cheaper than traditional PI.

Is this available now or still being developed?

Still in development. There are some beta testers out there reporting good results. Hopefully it will be released soon. I think the price point was going to be about $700.

O ok. Yea that sounds great. Thanks for all the helpful info. I was considering the cp-e port injection kit but this sounds promising and more affordable.
