Review on Innovative Performance Chip Power Programmer Replacement Parts best: Engines & Engine Parts by Kevin Zamora

I installed this chip on my 2017 Ford Flex the day before the 2600 mile trip. Before the trip I had 17.5 mpg. The best I had on the trip was 22.6mpg. It took a while for the chip to get past the learning phase, but mileage continued to increase as we drove. Oh, and I noticed an increase in performance right after installing it. This is an inexpensive way to increase performance and mileage.
