For the bully dog super users out there. I have had a BD GT installed on my 15 P4X now for about 8 months. I have it set up to view various temps, mpg etc. Can this tuner be used for any other options on these trucks? Like changing when the lights come on, or traction control just as an example? I am aware of the vehicle features like changing the idle (which I used to get rid of the vibration at idle), and changing the timing. Also when using the premium fuel tune, I have heard the VQ40 likes +2 degrees of timing. Should I add two degrees on the premium tune? What are the optimal settings in everyone s opinions to get the most out of this tuner? Thanks to everyone for their time and input!!
