It is no surprise MR Tuning and SFT are similar, they both get files from optimal remap in Bulgaria. They are base tune files that have no engineering in them at all. Let me know what you find with Reckless Motorsports. The owner of that company bought a used GDE tune last fall and started asking us a bunch of questions about it. I have a good idea he stole our tune. If you see similarities, I am all ears and will sue him for copywrite infringement. The vast majority of these tuning companies do not do their own development.
