Apps pretty good there are some changes to be made and perfected. I really wish I could make adjustments to the tune files when not connected. Most times in the car I have so much going on things are hard to remember be nice to be able to just hop on the app and grab the most recent saved file and make adjustments while I'm thinking about it at the dinner table like a great tuner would lol.

The dash part of the app has duplicate and missing numbers in the gauges on multiple settings. It's hard to believe what you're seeing. Please fix!
