1994.5-2003 7.3 Powerstroke DTC High Voltage High Current IDM

DTC High-Voltage High-Current units get two additional tweaks. The first step increases the output voltage to the injectors from 110 volts to 140 volts. 

The second step increases the current output by about 20%. This activates the injector quicker, holds it on (poppet valve open) more firmly, and keeps it on just a bit longer. The result is snappier acceleration and a more responsive truck. 

Note: If you are seeing a P1298 soft trouble code after installing IDM, this is completely normal for an upgraded IDM and will not cause any issues.
