aFe POWER 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. They are easy to install and require no cutting, splicing, or modifications. There are four power settings for on-the-fly adjustability and to accommodate any driving situation. This item works with ECM DPC-422 code and supports the following box codes: AGD, BKA, CNH, FIF, HAM, JLI, KRK, LVS, MNM, MRT, NVK and PMT.
