Kenworth w900 Detriot 475 vs W900 550 Cat Part 2

Nah, detroit have always pulled better. Stop being fan boys. I like CAT engines too, the truck I have now has one. But detroits always pull better unless they're having problems.

This is sad, almost not beleivable. That cat obviously has some problems. Either that or it's not tuned to 550 like the description says.
