This engine is very new and doesn't like modifications, but we did it anyway because we can make it better.
The Skinny:
Before MPG 28-34
After MPG 34-44
In town mileage might have been better but we had to use a thin business card to get this computer to act correctly. 30 lb paper worked well for the groove to be just far enough away that the computer handled it, not using caused issues with the computer. My hands were never trained by the master either, so it could just be me but when the wife breaks down twice in traffic you improvise even if it means you lose performance.
I will note this, the Intake is plastic and the throttle body is held on by brackets. You have to hold the brackets in place, while threading a nut onto a bolt at the same time. And when those bolts drop, they don't hit the floor because this car has a belly pan system. Oh yeah, ask me how fun that is.....
