Cheap Boost & Fuel Control for the 6.5TD

Back in March of 2000, The Diesel Page published a technical article (2000 Feature Articles volume, page 63) showing how to produce a variable boost pressure controller for the electronically controlled 6.5TD vehicles. This was simply a variable potentiometer that altered the 0-5 volt output of the boost pressure sensor - essentially fooling the computer into "sensing" a lower boost pressure than was actually produced by the turbocharger. This provided a means to increase boost pressure. That same article also discussed altering fuel delivery of the DS4 electronic fuel injection pump by varying the FSD calibration resistor value. Go here to see how easy it is, and to learn whether these concepts help increase power.
