I've got a 2018 Ram 3500 with only 40,000 miles, so I'm surprised I'm having problems with the turbo. It started acting up a few days ago and the dashboard screen shows it's only building up to 8 psi, then returning to 0 even when I jam the gas pedal. It's a fight going up hills on the freeway. Could it be due to any sensors? What is the best course of action in diagnosing and fixing this problem? Thanks
