MPG improvement. Does the stock tune run rich? Did the tune lean things out? I have seen similiar improvment on other cars but the stock tune ran pig rich to avoid detonation and etc...

I think most of the improvements are on the hwy and most of it is due to the ram air. Ive had several people tell me their mpg went up 1-2miles after installing the scoop. When cruising, your engine is just spoon fed air.
