Review on Innovative Performance Chip Power Programmer Replacement Parts best: Engines & Engine Parts by Justin Woolley

Naturally enlarges my 2011 Ford Flex 3.5L. Gasoline mileage at 1.6mpg. And also. I started getting intake air temp errors as well as a faulty crankshaft position sensor. Which I never had before installing this unit. Connection to the air mass meter. Not sure how this is supposed to work. But I do not think so. I followed the installation instructions. But. I wouldn't buy it.
