I am looking to get tunes for my 6.0. It's studded and bulletproofed. It's a dually with 4.10s and a stock turbo. I need a good tow tune and would like to go gear head but my 5th wheel is 16k. Is anybody towing this much with his 8k (13k studded tow tune? I do have to pull grades to get to the desert. Is it just a matter of monitoring egts?
