    Default Speedo/abs issues

    I sent a customer an autocal with "known good tunes on it and after he flashed it and did his delete work he went to drive it and has abs light, brake light in the dash and his speedo doesn't work. Now I know the speedo isn't part of the 6.7 ECM so I think he may have unplugged something he shouldn't but is there a chance the tune did this?
