I don't ever find them cool personally. They are a failed Supra tuner that tried to bully their way into into the BMW scene with lies, threats, and coercion.
I believe Marcus got a tune from ProEFI in an attempt to fix the problems of the HPF junk on his car. In the end as that video shows, the problem was much bigger then a poor tune from HPF.
