Congrats on the upgrade... does the M power button still change the throttle sensitivity?

Congrats. The gas mileage was a nice plus.

Did you do any before and after dyno's? Congrads on the extra power and gas mileage.

I believe the tune leans out the air to fuel ratio a bit during part throttle which increases gas mileage. I noticed the same with my tune as well (different tuner).
