Alright, getting truck back tomorrow. Have all the the Hardware that's required for under the truck. Question is, never loaded a tune on the truck yet and I'm planning a 10 day trip beginning next week. Do I just stick to stock, run 150 dpf on or go 250 off. Just don't need any surprises when we're out and not knowing what to do. Wife said I'm scared, no nervous was my reply. Suggestions? I'd rather just do the 250 and be done with it. Pulling a 5er and heading north.
