"Updating the tuner online ate up the most time for me. One I don't have a personal non-Apple computer, so I had to do the update on someone elses. The forum with the updates is fairly unclear about which files are the most up to date within the 6 pages of posts. After these initial issues the installation on the actual vehicle was quick and easy. The tuner paired with a CAI seems to yeild a more aggressive vehicle. The code reading/clearing is reason enough to purchase the product." —Brad J from Chicago, IL bought a DiabloSport inTune I-1000 Tuner for a 2008 Jeep Grand Cherokee.
"Tuner is awesome. Speedo calibration is great, it's about time someone offered this tool. Performance tunes eliminate throttle lag, sharpen shifts, and greatly enhance launch. Unexpected surprise-performance tunes also increase MPG's!
I love it, my rig is quicker than it was stock even with the added weight of aftermarket skids all around, and 32" tires!" —Robert G from Rolling Meadows, IL bought a Superchips Flashpaq Tuner for a 2008 Jeep Grand Cherokee, 5.7L Hemi.
