We did our first trip close to 1900 miles with a loaded 24ft car trailer with a my C7 Cat powered coach after doing a deep maintenance which included a near CAC cooler, new radiator, plus all moving parts behind the radiator. The CAC had a bad leak and I was loosing turbo boost. I did think I was loosing and power but I was badly mistaken. With the proper turbo boost I have much better low and high end power. I can cruise in the economy mode and if the terrain isn't to steep and it holds it's rpms now without down shift. My message is that if you seem to be short on power check your turbo boost. One my thing I forgot to mention my trailer behind is now almost soot free,
Linear Mode
