100% of your salary in a satellite office is about visibility from the main office. You should be giving talks to groups of people in the main office, partnering with top people in the main office to share best known practices, and having strategic catch ups with top management in the main office.
In most large corporations (with some notable exceptions) the way pay rises are determined is that your boss will have a budget for his team (possibly $$$ but possibly just 'ratings' that fit a distribution). Then their boss will review all the teams under him to make sure the distribution and budget for their organisation is satisfied and this goes up and up until you reach departmental level.
So you don't just need a good rating from your boss, you need everyone in each of those hierarchical discussions to know who you are and back your value. Because if not, it's very easy for them to cut 10% off the pay rise of drone 7b to give to Johnny star performer.
As well as that there's another dynamic. If the people in those conversations think you are good, then your boss is under pressure to say you're good in order to demonstrate (s)he is a good manager who can identify talent and take the hard decisions necessary to keep the best people.
Basically, you have to demonstrate value rather than provide value.
