Cobb does not make a OTS map for E85. You're going to have to run at least 850cc injectors with an upgraded fuel pump at minimum. Contact local tuners in your area to see if they protune for E85.
Cause E85 uses 30% More Fuel. Fuel Pump, Bigger Injectors, some kind of boost controller (3 port boost solenoid is my recommendation) and a tune is a must on E85. Instead of asking all of us, you should be asking a local tuner in your area if there are experts in tuning for E85.

Sup ralph you will need injectors and fuelpump and pro tune you could do 850cc minumum but i would do 1000cc ID Great injectors a lot of people running that injector on e85 with stock turbo.

Is there a general rule of thumb for injector/pump ratio per approximate power increase? I get it'll be more complicated than that and that more is of course more, just curious what the rough angle of trend is.

Hey Ed, for running E85 you recomended me a while back 850cc as a room-to-grow size for injector alongside a Walbro 255 pump for a TD04, 2L motor (04 WRX).

Is an aftermarket fuel presure regulator and/or pressure gauge needed, a "good idea," or not altogether not necessary?
At what point might either be needed, if at all?
