Hello, I have a 2021 GTX 300 Limited that after adding octane boost, the ski defaults into Sport mode. The back story goes like this.
I bought some octane boost to try and after adding some, the ski ran horrible. It started mis firing and bucking at idle. It only would run in
Sport mode. So, I drained most of the gas out and added fresh 91 and the ski ran much better. The problem now is that it defaults into
sport mode on startup. I don't know if this is a coincidence and a separate issue or the cause.
Is there a way to reset defaults or is this a bigger issue?
