I purchased an upgraded towing turbo for my 2012 Ram. The purchase and core return from turbo time was great. The turbo is top quality as were the parts associated with the included install kit. As for the function of the turbo it works flawlessly. Being slightly oversized you wouldn’t notice it in spool time. The power curve is defined designed for towing. The boost is solid. It does feel as though it may have taken a tiny bit off of my top end but man the power is fantastic during towing as is the exhaust brake function. Functions better than stock for sure. They advertise 25% more exhaust brake force. I believe that to be on the button. Very satisfied with my purchase.
