2010 Ram 2500, 4×4 QCLB. EZLYNK with MotorOps tunes, deleted, 5" exhaust, Wehrli 4" intake
So I've previously owned several 5.9L dodges but just jumped into my first 6.7L yesterday. A beautiful 2010 2500 CC LB 4x4 Laramie. So far, I've run into two issues. I was told it used DEF but there's no fill port next to the fuel fill port... I just found out earlier today that i have no heater (blows air but no hot). So I'll be poking around at that. I have spotted some metal tubing that hooks up to my stock exhaust but I'm not familiar with the kind of technology that these newer Rams have. Any insight or advice would be great! Looking to increase my MPG but not sure if i need to do an EGR delete, because I'm an idiot hahaha Thanks!!
