This chip’s simple installation brings enough horsepower to throw you back in your seat. With improved shifting, efficiency, and overall drivability - it improves your vehicle’s performance in virtually every way.

Increased Power and Performance:
SCORCHER HD performance chips deliver significant power gains by increasing turbo boost as well as optimizing fuel injection timing and pulse width. Unlike many other chips on the market that "flash" the ECM, our performance chips receive data from the ECM and alter signals appropriately.

Easy Installation:            
After removal of the vehicle's ECM, the installation is a breeze. Remove the cover to find the ECM port connections, clean the ports, then simply slide the chip into the ECM. No cutting, splicing, or modifications of wiring is necessary.

Four Power Settings:
A knob can be mounted in the cabin for easy, on-the-fly adjustability to accommodate any driving situation. The four settings are:

  • +50 Horsepower
  • +75 Horsepower
  • +100 Horsepower
  • "HOT" (up to +140 Horsepower)

Fitment Note:
This part number works with ECM DPC-492 code and supports the following box codes: NQW, QLI, SHT and MAP.
