Performed as promised

Installation wasnt as easy as stated, had to trim my "factory off road cover". But once that was done, this unit woke up my 6.0 LQ4. Had it for a while now, only bumped mpg by 1 gallon,,,, but worth it! Especially when I show other H2 drivers my readings!

Awesome piece of equipment but not for the novice.

Awesome piece of equipment but not for the novice. This tuner has the ability to fine tune almost every aspect of your vehicle. Without knowledge of the items it can tune for you I suggest: either use the installed program or download a proven program, or change it 1 increment at a time and thoroughly test the tune before adjusting again, just to avoid costly damage no covered by any warranty. Monitor the settings with the unit and create a log file and keep it for reference. With oversize tires, cold air induction, and cat back exhaust and predator i am able to improve my gas mileage by over 4.4 mpg with in town driving. And performance thru the roof :-)) AUTOANYTHING was GREAT TOO!

Lots of options

Really a nice device. I am amazed at all you can monitor with it. My main reason for purchase was to monitor the transmission temps when towing my 17 ft travel trailer. But I'm also monitoring fuel mileage and throttle position. I only gave 4 stars because the included velcro for mounting allows for too much vibration. Replaced it with a 3M Command strip refill.
