Hello everyone I have a 2012 cm2250 set at 550 hp and 1850 tq. Power is ok but the acceleration is terrible. This truck used to be a company truck. Turbo lag. I'm out in Arizona
Thanks

is it de-mandated (deleted) or not?

maybe some history / background on the issue, etc?

How about the gearing in the rear end? Automatic or manual? Make, model, mileage? Service history?

Depending on what year but these newer ones from many company have variable rate vehicle acceleration management need to be disabled
