I've been tweeking my tune, not sure if there is anything I could do to improve what I've got. I'd like better fuel economy but also performance. Multiple tunes is definite. I've currently got a 3.4 inch pulley on it for 6-7 lb boost. I've also got a 2.8 and 3.0 inch ones too. Maggie MP112 mounted. Running a 4L60E
