  • my truck has EFI live already tuned on I believe it. It’s on the 65 hp tune but I’m not 100% sure. I bought it like this. If I was to install the switch, I have a brand new tuner with EFI livethat shows me all of the tunes. If I was to install the switch, I believe I would have the ability to on the fly tune, correct without installing the new tune I could probably return that I’m just confused and not 100% sure

    The switch will allow you to SOTF, only  if you have SOTF tuning. please check with your tune writer.

  • My switch broke. Can I just replace the switch or do I have to get it tuned ? I just bought the truck and didn’t get any thing to put stock tune back in
