So Im new to the site and performance mod world. I have a 14’ Ram 2500 with a 68 rfe trans. Im looking to do some upgrades. So far im going with the banks cold air intake and monster ram intake system, 5” flopro exhaust with muffler. As far as tuners, Im either going with with MM3 or EZLYNK...I think. For some reason im worried about the egt pulling my boat (5k lbs and eventually 8-10k) over two mountain passes on our way to our vaca spot. Is this something i need to worry about? If so what temp (and for how long) should I start getting in to “panic” mode? And whats the fix if i'm in the middle of pulling up a grade?

Also can someone help me understand what “full locked shifts” means and why that important?

Also any advice as to what delete kit to get or anything I would greatly appreciate.

Thanks
Ryan
