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!

2014 Sierra 5.3

Reviewed By Ronald R (Boise, ID) Reviewed for a 2014 GMC Sierra —12/22/2014 7:25 AM

Truck is a lot more fun to drive now. Throttle is more responsive, holds gears longer under full throttle, and shifts do feel firmer. When getting on the gas after a turn, the truck seems to be in the right gear and accelerates better. Overall I am very happy with it.

T-1000, fuel saver

Reviewed By Francisco V (SAVANNAH, GA) Reviewed for a 2006 Chrysler 300 —12/1/2014 8:32 AM

Got the T-1000 in preparation for my trip to New Jersey from Savannah GA. I went through a couple of the different modes and the fuel saver programmer saved me a lot of money not to mention the car seemed to perform as normal. I used the 93 CAI settings and felt an immediate difference, for my trip up north I used the fuel saver didn't feel any less horsepower but I saw the numbers when I looked at how many miles to empty I got. Changing your setting is simple and takes 1 min top. HAPPY!!!!
