Kenworth 501 with a Cat C-15 550hp 1850 ftlb

Kenworth 501 with a Cat C-15 550hp 1850 ftlb. Used for medium heavy haulage. Now running 1 1/2 gears better then when it had 4242 injector codes in it (correct codes were installed prior to tune).

Recently carted 85 tonne up the Toowoomba range in top gear bottom box. Absolutely no temperature issues. The customer has also noticed a significant drop in fuel consumption.
