Paccar MX-13 tuning

[Running rough]

I will not deny that I am partial to the red moter because that's the moter that I have always driven, however I do have to admit that probly the most reliable platform for high torque and power are undeniably caterpillar, and if cummins continues to build inferior products, they will only hurt themselves, I would if a company produces a product and it is know to have problems or defects, they would do everything in thier power to improve and eliminate issues, otherwise people get fed up and move to a competitor product who realize that you don't win customers by building inferior engines,
