While towing I noticed that my engine temp was always above 210*f and pulling a grade would go to 235*f plus, the light would come on.

My Truck has the BlackMaxx and 5" pipe done to it. Power setting was stock.

My oil pressure gauge is also acting up, all of a sudden it was stuck on 0. truck has oil pressure verified by a mechanical gauge. Replaced sender no change. I have not taken it to the dealer yet because of the mods, although they are aware that I did mod's, i told them when i bought it.
