    I'll give it a shot, but internet connection shouldn't be necessary as all of the data is coming from the vehicle (not the internet). I've been using HPTuners for probably 15 years and I've never...

    2004 Silverado has a separate TAC module just like the C5 (just different version) as it's still a Gen3 with an 0411 ECU. So for whatever reason, the C5 TAC is okay with adjustments but the truck TAC...

    I just got my mpvi2 pro in the mail today and ran into this issue. I had to resync the interface and be connected to internet for it to work (no idea why). It seems the JTEC tuning is flaky.
