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!

Worth it for towing

Reviewed By Michael Z (Wolcott, CT) Reviewed for a 2011 Chevy Silverado —4/9/2015 6:04 AM

I saw the reviews for the I-1000 and decided to give it a try. I saw a small difference in the 87 tune so I decided to try the 93 (Diablo tune). That made a big difference. I'm now able to climb hills in 5th where the truck used to downshift to 4th to climb the same hills. And by climbing I mean actually accelerating in 5th while climbing those hills. have also seen a 2 mpg increase. I'm going to have a personal tune done as soon as I can come up with the cash. Well worth the investment..
