Yes, I've one in my truck for about two years now. While the throttle response is noticeably improved, the mileage increase is nothing to write home about. I've hand calculated over a year or so, and can safely say 1-2 mpg, not enough to mention.


They are very quick to say in their user guide to TAKE THE MODULE OUT OF THE TRUCK WHEN YOU TAKE IT IN FOR SERVICE. The Dealer I take my truck to doesn't mind if it's there, but lots of others do and will ding you for it.


That all being said, The improved throttle response was enough for me to be happy. I'll wait till my power train warranty is up to do something a little more invasive.
