I didn’t notice any power increase or any increase in gas mileage after 500 Miles of use. They said to give it 150 miles to evaluate and I did but by the time that happened the 30 day refund time limit was up. After a few months I unplugged it and have not noticed any difference in the performance of my Tacoma before the chip or after the chip. I would not buy this chip again.
