I was at a shop last week and they were trying to first update the operation system of the ITSX which took 3 hours, then they couldnt get the data to load.
I tuned one full car, and strapped down another, before they gave up. lol
If you want tuning toys, those are ok to have. If you want platforms to actually design a custom calibration for your vehicle, go with HP Tuners or EFI and dont limit yourself.
