The Hot tune has made my 3.0L CRD act like an SRT8. My fuel economy went up about 10% (from 20 MPG to 22 MPG in mixed driving). I bought both tunes but the Hot tune hit my target of 20 MPG towing my 3200 lb. popup (70 MPH - cruise control on) so I've never installed the Eco tune. The GC is a ball to drive with the Hot tune and still delivers very good fuel economy even when you're taking advantage of all that low end torque (455+ at 1600 RPM vs. SRT8 420 lb. ft. @ 4,800 RPM - a period chassis dyno test indicated that the factory rating of 376 lb.ft. was conservative: http://www.trucktrend.com/news/0711dp-2007-jeep-grand-cherokee-crd/ ). I asked a lot of questions before buying this tune (I was an engine cooling engineer at GM). Bottom line: GDE tests like an OEM including hot ambient trailer towing. You can have confidence that the GDE tune won't grenade your engine towing a trailer up a long hill at 110 F. I highly recommend this tune to wake up your stock engine and get better fuel economy.

I just installed the hot tune on my 2007 Jeep Grand Cherokee. What a difference, lots more power and the torque curve is much smoother. Before, at low RPMs entering my garage, it would sort of jump ahead when just a small amount of fuel pedal was applied, almost to the point of being dangerous. After the hot tune acceleration at virtual any RPM is smooth. I just wish I would have installed the hot tune before I spent $3,800 to pull and de-coke the intact manifolds and replace the swirl valve motor. I am now going to buy the hot tune for my wife's 2005 Jetta TDI.

I'm lifted with Rough Country leveling kit so 2"/3"; have 33+" tires; roof rack with fullsize spare on it. I was down to 18mpg average with stock tune and AC on. I'm now averaging 25mpg with AC on! Not to mention the the Jeep squats and takes off faster than many V8s now. Wish I had done this years ago.

This was a fantastic decision! I get ~22mpg on the highway (driving 75-90mph) and in town I get ~19mpg - these are great numbers!! Running my 07 grand cherokee on the trails I get ~17mpg. The best part - hitting the accelerator and being thrown back into the seat. The torque is out of this world! This is the best improvement I could have done and I have not regretted this decision, not for one minute. Love this product and recommend it to anyone that has a diesel... Definitely a do-over!
