Thanks for the reply Ænema! I'm new to the Cobb, is the ATR = Access Tuner Race Beta from the Cobb website?

How hard would it be to adjust the fuel scalar? I assume I would want to add just a little more fuel since the E85 leans out the mix, but how much more would it need to be bumped up? Or is this where running logs (also will be a first time endeavor for me) and checking my fuel trims comes into play...

That's a whole other topic there lol, is there a post in this thread detailing how to do logs and check fuel trims etc?

Thanks again for the help man, much appreciated!
