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..
