TD@ in 2008 Rubicon
Does a lot of cool things, Was a little disappointed that it has no control of the Rubicon sway bar disconnect, as some reviews state. It will turn off the warning light it the user has bypassed it in some other manner. In addition, locker control seems to be there in 2wd and 4 hi also, but in mine, I have to be stopped to engage the lockers with the td2. The switch allows locking while moving, but only in 4low. I have had the td2 lock up a few times and require a power cycle to reset.
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.
