I've been recording this as well in my 2.2L. The best I've managed, with straight highway driving, was around 23.5 mpg. Dirty 02 sensors, I'm thinking?

oh hai, i haz an EJ22. I want to make it rumble more like a WRX but I'm not really willing to spend anything, so i dont see that happening. oh well!

:facepalm:

Dude, if you have to ask, you really shouldn't do this yourself. I'm not trying to be a d!ck or anything, but you're barking up a very tall tree. Just because you have a turbo sitting on your shelf doesn't mean you're "almost there", as you need to integrate this into an N/A motor, which is much easier said than done. You're better off just swapping in a turbo motor and modifying from there.
