Works Great. You can Really Tell a difference in acceleration. Havent had it on long enough to check mpg.

I have a 2000 GMC sierra with a 5.3 and thought I would give this a try. The installation is very well documented and it took about half an hour. It's a very simple concept but I haven't driven it enough to have any real honest results as to its claims of better performance.
