YES. We lock our tune files. We have thousands of hours of R&D to develop the intricate understanding of the platform that we have today. You will not be able to edit the tune files that we send you. This is nothing personal, we simply are protecting our company, business, and information.  Unfortunately, theft of information is rampant in the performance tuning market and we are doing our best to protect the information we have worked hard to gain. We also ask that you please not share our information with others.
