I drove it today. It is a beast, way more power than the idi that was there. It drones a bit on hills so I ordered a 51" muffler. The engine is quieter than my brothers 6.0 power stroke. Boost can hit about 20 psi, and it fuels clean through 3200 rpm. It feels like a superduty with where the seat sits an inch higher. The brakes and power steering work awesome, hydro boost is the only way to go.
