Got the Super Chip programmer today. I like it! Easy to use and I felt a seat of the pants difference. Even with 5:13's mines been a dog over the last couple of days since putting on the 37's. Ofcourse Im driving a brick in 30 mph winds.
I set it on the 89 octane setting and found no detonation or pinging. You hit the throttle and it goes. It also appears to have gotten rid of the lag that happens when you push the gas. I'll have to play with it some more but there are fan settings, performance settings, transfer case settings for front and rear, tire and gear settings and I think Im leaving a couple out. Plus unlike the competition it comes with a USB so you can download updates.
I actually went to the R&D location and picked it up. They came out and programmed it for me and walked me thru it. I like their customer service.
We're giving a couple of these away at Jeep Beach so hopefully a couple of you will walk away with one.
