I have a 2015 Frontier Pro-4X. Currently I can only engage the rear locking differential if the truck is in 4WD-Low. I know that tuners like the Bully Dog GT will allow for the Jeep Rubicon to engage it's rear locker while in 2WD and 4WD-Hi. Is there a tuner that has the same function for my Frontier Pro-4X? I emailed Bully Dog with this question last week and I have not received a response. I called Bully Dog today and the support guy stated that the tuner for my truck may have the locker function but he could not guarantee it. Any help is much appreciated.
