Here's an idea if you got a 23 and wana give it a little boost! I did this as a late an early winter project about two months ago. I added a homemade ram air through the front grill. It has worked great since then. It even zips along in the snow and rain. No sensor adjustments needed. heres part II of the series, they are real short as I need new mac software to and a better camera for my next project. thanks leave any comments you like.

 

Gets awesome gas mileage on highway now plus quick takeoff way better than before

 

Idk about your testing, but these guys have done massive dyno runs testing car mods. lol
