Hello all I have a raceme ultra, recently
updated my tuner to the latest software. After the download I installed into the truck, added a 60hp tune with trans tuning for stock and programmed the ecm. After it was finished I noticed the whole layout changed. After browsing for a bit I noticed there’s a button that says “switch”. It’s an on the fly tune 0-5 with stock, row, street, performance, race. This is the part I don’t understand. If I downloaded a 60hp tune to the ECM, then what are the values for the 0-5 switch tunes on the fly? Also noticed with the new update my def fluid went from reading 0 to 100% ??*?? Any help appreciated thank you !!

truck has egr block off plates/DPF/def 5” exhaust and air intake.
