Along with some local Subaru guru help, I installed the Fiveo 1200cc Injectors today:

Took about 3hrs or so with two people working on the install. It was a pretty big pain to get the driver's side bracket out. Injectors went in without any problems.

Build Thread: xluben's 2011 WRX 5 Door Build Thread: E85 Tune!



Hoping to get a touch up tune once I get the rest of the pump gas out of my tank, and the stations switch to true E85 for summer. Should be a few more ponies left to be had. For anyone considering E85, go for it! You can see the gains I got over a normal Stage 2. Pulls soooo much stronger now, and the power band is great  

*Disclaimer: Virtual Dyno on the Dynojet setting reads pretty high. Figure about 330WHP/360WTQ on the Airboy spreadsheets or COBB's Mustang dyno. The car gained 50WHP and 40WTQ over Stage 2 with the E85 tune.

Approx Prices:
Premium: $3.70
E85: $2.80

Approx Fuel Economy:
Premium: 20MPG
E85: 16MPG

Price per Mile:
Premium: $0.185/mile
E85: $0.175/mile

So right now I'm pretty much breaking even on cost, slightly ahead at the moment. If my mileage dips to 15MPG or E85 gets more expensive (in relation to Premium) then it swings back the other way. It's close enough not to be a concern at this point.
