About Our Programming

All Krazy On Highways Inc Custom Diesel Tuning is developed in house by our team of engineers and are put through hundreds of hours of testing prior to being made public. Our tunes are custom, non-generic type tunes unlike those you will find through many of our competitors. This means that rather than throwing a random flash file into your ECM, we personally go through your engine’s original settings and reprogram them to deliver the performance that you are paying for.


Our tunes are designed for off-road or competition racing use only. Use on Provincial / State and Federal Highways is a violation of the EPA Clean Air Act. The Clean Air Act can be found at http://www.epa.gov/air/caa/. This document contains in detail what are considered to be violations of the CAA and corresponding penalties for failure to obey and should be read in full before purchasing and installing any of our off-road, race use only products or services. Ensuring that all emissions, noise/sound, and speed/use related laws are followed is the responsibility of the Buyer(s) and Installer(s). The purchase, installation and use of our tunes indicates that this disclaimer has been read, acknowledged and understood fully by both the Buyer(s) and Installer(s). All prices listed cover only the cost of the ECM Tuning. Parts and installation costs are included separately.
