Saabs use some kind of tuning system that not many people support. I think it was called T8 something. Tritonic or something along that line. As a result there are very few tuners in the world (JZW, VTuner, Hirsch, MapTun, and BSR) I chose VTuner because of excellent customer support and low pricing. JZW requires that I send my ECU in for tuning while VTuner, Hirsch, MapTun and BSR include a handheld unit that saves your stock tune and include their tune. BSR has been iffy and is over 1,000. MapTun, barely heard anything about that and VTune is the cheapest and obtains the most HP after extensive research and work.
Only two more days before it arrives.
