Has anyone used the Superchips micro tuner on their Durango? Like it?

 

I really like it a lot on my 5.9L. Small performance gain on the 87 octane and a very noticable power gain mid-range on the 91/93 octane program. Nice having the DTC reader built in. Well worth the price for what you get. I bought new on E-Bay for $309.00
