I have a 2012 wrx hatch with a turbo xs bov, aem intake, cobb ap ots tune, and a tsudo catless downpipe coming soon.
Will I be able to add a few gallons of e-85 to improve performance without having aftermarket injectors/fuel pump?

Deatschewerks makes a drop in replacement for 08+ I'd go with that and the same brand injectors

Every set of 1300cc DW injectors I have seen (over a dozen) have failed, some destroying expensive built engines in the process. I personally went through three sets of them before I switched to Five-O 1200s. Honestly, I am amazed they are still selling them. They have so many returns on them that they can't even keep up with the exchanges. The last set I returned took over a year for me to get my money back.
I would argue that an upgraded TMIC isn't essential when switching to e85 because of the cooler burning properties of ethanol. It would still be a worthwhile upgrade simply to reduce pressure drop though..
The upgraded TMIC isn't so much for it's cooling, but the pressure drop and the fact that the stock one has issues with the plastic endtanks; an ethanol tune could push it beyond it's physical capabilities.Originally Posted by MainFrame
Get rid of the bpv until you have a tune that supports it.
