Hi, I've Just bought a 2006 Damon Tuscany with a Cat C7 350 hp turbo engine.
Although driving it home from the dealers (400 miles away) it ran just fine, i couldn't tell if the turbo was kicking in or not. There does not seem to be any type of 'surge' or increased speed with the accelerator pedal pushed to the floor. Going up hills it would lose speed and even slow down to the degree that I would need hazard lights on. This was all freeway driving.
Am i missing something and expecting too much?
