Got my 93 octane tune done @ Injected Engineering last Wednesday. I have the Steeda CAI, Solo Performance Mach Thunder catback, 170 degree thermostat and nothing more.
Car put down 415RWHP/386RWTQ SAE. Temp was 86 in the shop and 90%+ humidity. I am very happy with those numbers. Car pulls so much harder from 4K upto the 7400 redline. I wasn't expecting a 93 tune to make this big of difference but it is night and day difference.
They loaded up their base Flexfuel tune and I am now running E85. Almost thru my first blended tank of 93/E85. I'll run another full take of E85 and head back over so they can tweak things and re-dyno. Can't wait to get this dialed in on E85 since a brand new station open 5 minutes from my house.
