I can't find VP16 on their website.
I think that's overkill...94 or 96 octane will likely be enough to allow the knock sensors to give you the max allowed spark anyway.
Also important about the fuel is that the stoic point is similar to that of your pump gas, otherwise your fuel trims can be off and that could have the same effect as adding too much ethanol which LMS says not to add on their tunes.
