2021 Ram 3500 H.O.

We’ve deleted our Kenworth and blocked off the EGR. The thing still has no over abundance of cooling. The same can be said of our pre emission Peterbilt. A hot day and long hard pull can get these trucks to the point of red warning lights. I was under the impression that removing the emission equipment on the newer diesel pickups doesn’t do much for fuel economy anymore? If it’s true that a Ram pickup has cooling for 500 hp deleted yet only 400 hp stock then 100 extra hp is being lost into the cooling system. So removing the emission equipment without adding any addition fuel would offer a gain of 100 hp. We should be able to do a delete on our trucks and see a 25% increase in fuel economy without attributing anything to the loss in efficiency that the restrictive exhaust is causing. Plus there is the lost fuel used to clean the DPF. All tolled a deleted truck should get substantially better fuel economy. I really would be interested in seeing a before and after deleting fuel economy comparison done. For those who plan on putting 300,000 miles on their truck deleting could save between 10 and 15 grand on fuel over the life of the truck.
