aFe Scorcher HD performance chip for 2002-2003 Ford F-250/F-350 Super Duty 7.3L Power Stroke diesel trucks with automatic transmission. It slides into the ECM port and reads then alters signals to raise turbo boost and optimize fuel injection timing and pulse width, adding power without flashing the ECM. A cabin-mounted 4-position knob switches on the fly between +50, +75, +100 and HOT (up to +140) horsepower, and the chip also firms shift points. Works with ECM DPC-462 and box codes BXE, KEK, NWM, PBY, PRW, TMA, VDH, VDU and QLI.
