Got the T87 upgrade for my 2014 LML and I am very pleased with the performance definitely a noticeable difference...it's like I got new truck....only issue I have with it truck at times inadvertently goes into tow mode without me pressing button on the shifter. I just push button to take it out of tow mode.
