About Our Programming

All Krazy On Highways Inc Calibration(s) are developed in house by our team of engine calibrators and are put through hundreds of hours of testing prior to being made public. Our calibrations are custom, non-generic type "tunes" unlike those you will find through many of our competitors we modify your existing engine operating systems. This means that rather than throwing a random flash file into your ECM or flashing an updated OEM file, we upload your engine’s original settings and make modifications. We will maximize and deliver the Economy/Performance your after. We can also set limits if the unit is operated by an Employee or Teenager..


 Some Calibrations 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.
