Just installed the hot tune on my wk. It completely blew my mind! The power and throttle response is amazing. Haven't drove long enough to see mpg gains but even if i don't get better milage i will be more than happy with my investment. Transmission shifts much better and turbo lag is gone it feels like a new jeep. Great job GDE!!

What a difference the tuning made to wake up the ole jeep. You guys are outstanding. Great customer service, fast shipping, and all my questions were answered before i ever pulled the trigger on buying. Communication was same day or next day after buisness hours. I dont think i could name one bad thing about buying. I will be back for all my tuning needs. Only negative i can see is that the tuning tool does not have built in data logging which would be really nice to have. Maybe in the future that could be added?

Thanks for a great product and support! I have a 2008 Grand Cherokee and purchased the HOT Tune for it. I am thoroughly impressed. This tune has brought this engine to life! The throttle response and feel of immediate power is the best. I saw an instant bump in fuel economy also.

I have had my 07 WK CRD for nearly 2 years and have traveled about 32.5K Miles. I installed the ECO tune less than a week after purchasing the vehicle. I have averaged 23.5 mpg over the above distance (all seasons and conditions), and this tune did wonders for drive-ability. I genuinely love this tune. I am also a repeat customer: prior to my current WK, I have 2 Jeep Liberty CRDs, and I put the ECO tune on those as well. I've trusted all my vehicles to GDE for the past 8 years, and have not regretted it for a second. My future plans for my WK are to do an axle swap (-3.73s for +3.07s) and add the Hot Tune programming. Estimates push my mileage to move closer to 26-29 mpg overall average with those future changes. I know that GDE will be with me all the way. They are great, and their products are fantastic. -Rick Kulesh Rhode Island

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.
