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.

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

• Stock
• High-Idle: Used to reduce wet-stacking leading to excessive engine wear
• +50 Horsepower
• +75 Horsepower
• +100 Horsepower
• “HOT” (up to +133 Horsepower)

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