| What power setting are you running? Please define moderate acceleration. I wouldn't worry about your engine or turbo, but your tranny is a different story. If you are running a higher power setting and pushing it to merge into traffic, you could limp your tranny when it shifts into 5th. When was the last time you changed your fuel filter?? Could be starving the truck of fuel, but I would think you would get a check engine light, but not always.
