I didn’t change much. Although in EY there is a tendency to follow minhag haGra on certain things (but not all), for example the shir shel yom on yamim tovim is different, omitting v’shamru on Friday night, no tefillin on chol hamoed, even ashkenazim say ein kelokeinu/pitom haketores on weekdays, etc).
I am not sure where you live – but in my neighborhood I would say half the shuls daven ashkenaz (including mine) and half sfard.
