Very easy to install & remove if need be and far less time than changing the tunes on other programmers. I noticed that most of the power gain was in the higher rpm range. there was a less noticeable increase in low end torque. Can't say about any increase in fuel mileage yet. I have a cold air intake, high flow exhaust & a TBS installed.
