6.4L KEM 7015 X4 Price: $849.00

6.4L SCT XCal 4 (7015) with four custom KEM tunes. We have been tuning the 6.4L longer than any other company and know what works and what doesn't. The tuner comes with 4 power levels: 40, 75, 150, and 210. Please Note: These are on highway use files only! It will require that all of the emissions equipment is installed and operational on the truck. Attempting to use this on a deleted truck will cause issues!
