I own an 01 F250 7.3 Powerstroke diesel (my first diesel truck), and it seems like its lacking the towing power I'd expect from a diesel engine. Before this truck I had a silverado with the 6.0l gas engine, and I havent noticed a significant difference between the 2 trucks while towing around a loaded trailer. Anyone have any ideas at what to look at? If I put the accelerator to the floor I dont get any black smoke either which I always thought I should be able to. Thanks for any advice.
