What kind of info. gets adjusted or changed?? There were 406 bits of info loaded. Please use words I can understand, I'm not computer saavy ,Thanks!

 

Updates are more or less changes to make handheld tuner as compatible/functional as possible. More than likely they SCT is just keeping their tuner current with windows/Mac updates and/or new dyno software.or apps.

I do know that you ALWAYS put your car back to stock BEFORE updating the tuner. There is a risk you lose your stock tune for good otherwise.

FWIW, 406 bits is a very small change and more than likely something you won't be able to notice anyways
