Bullydog for Jeep JK
The Tuner is well made and instructions are very good. Only downsides are the it only has 4 maps for my Jeep JK, the head unit is small, and then menus are confusing. Overall it does what it says it does and I went from 14 MPG to 17.5 MPG. A pretty good bump for a Jeep. The tire size tool fixed my laggy speedo(-5MPH) back to the correct speed. Overall worth the money, but it needs a little more work like more maps and a little bigger screen.
Mike from Texas
I recently took a 2800 mile trip and I only used 80 gallons of diesel going and coming round trip I get 40 miles to the gallon plus on the 6.7 Dodge Cummins diesel I'm very pleased with it I would recommend it to all diesel enthusiasts that want to save money on fuel and not only that I did not even use Maybe an eighth of a tank of DF fluid with that being said the power is all still there it works great I love it and I would recommend it to anybody very easy to install my truck has a 2015 Dodge
Great Tune-Up for your Truck
I have a 2001 Chev Silverado 2500HD. It has been recently upgraded to larger tires an needed a boost to handle the larger 33" tires. The BullyDog did the trick. Great product. You can program your tire size. gear change for your differential, your transmission shift points. I chose the pre-programed tow setting for my truck. I gave me the ability to easily pull our travel trailer on vacation.
