ADP EFI Live Tuning is designed to take what the manufacturer left on the table with modest tuning and give that back to you in the form of increased fuel efficiency, power, and driveability. This tuning is designed to put a smile on your face, not break the bank, and give you increased capability whether your truck is a daily driver, tow pig or weekend hauler.

Testing and Validation

During our development and testing of ECM and TCM Calibrations for the 2.8L Duramax Canyon/Colorado we traversed many climates. Testing included driving at 6412ft above sea level in Manitou Springs, CO all the way down to 331ft above sea level in Daleville, AL. During the course of our testing we drove unloaded on road and off-road experiencing temperatures from 102F down to -17F. During our towing test we loaded the vehicle with 800lbs of cargo and connected a 5500lb trailer and began a cross country drive. 1200 miles in total one way for our initial tow test. We also took our vehicle to a state certified emissions testing center for a dyno based test. During testing the vehicle produced 02% Opacity or better at Zero Shift, 40mph, 50mph, and 60mph testing. Emissions controls received a Pass status in Electronic Engine Controls, Catalytic Converter, PCV System and EGR System. Overall results were green across the board with passing results in the state of Colorado on 12 Septemeber 2019.
