You will not loose 10 bhp and 10 lb torque. This is a diesel not a petrol car so you probably will not loose much if any peak bhp but the torque lowered to 320-330 lb you would get a lot less smoke when the turbo is spooling up. As i PM`d you already smoke is unburnt diesel.What Jabba is doing is adding too much diesel for the amount of air the turbo is sucking into the car especially when off boost in a bad attempt to get the turbo to spool up quicker. It produces high torque figures but makes the car smoke like hell. Peak bhp which is reached much later in the rev range when the turbo is on full boost shouldn`t be affected really as you will still be injecting max amount of diesel, it`s just that your injectors will not max out so soon. Sorry but in my humble opinion that is nothing more then bad mapping but bhp and torque figures sale not how the car drives or what the bhp/torque graph looks like. Sad but true.
