Does anyone have any experience with these Superchips? I am intrigued by their claims. I have a Milan I4 automatic, If all I got was better throttle response, a little more jump and gas mileage I would be happy. However, I am a little skeptical and I can't get myself to part with the $$$ the BAMA chips go for from Jusnes Modified (although I think they would work fine). Any thoughts?
