Another consideration is the increased temperature created by boost and increased fuel supplied by adjusting the injector pump. Exhaust Gas Temperature sensors can be fitted if serious boost is applied. A meter on the dash can then let you monitor the climbing temperature. You should find lots of info about that on the net. ( EGT Probe ) . Too much heat = loss of piston top.
A normally aspirated diesel does not have boost compensation on the injector pump so when you increase the pump settings to allow more fuel flow then a bit of black smoke on acceleration can be expected as the turbo will not have had time to wind up and deliver more air to burn the increased fuel supplied.

There is a famous Fearsome Turbo Zetor that does the international circuits in Tractor Pull competitions. ( started out as a modified crystal ). That is impressive with an exhaust cloud that covers the crowd watching and can even hide the tractor with its hundreds of HP. The turbo on that is massive - but that is a competition vehicle with loads of expert experimentation. He also blows thing up from time to time. All good fun- no doubt about it.
I have watched it perform and the crowd following is great. It puts Zetor on the map.

My 1 cents worth. There must be many who can share their successes and other learning experiences.
