Just wondering if you guys can help me properly guestimate how much power I'm losing up here.

Generally for a boosted engine (SC) it’s roughly 1.5% per 1000ft of power loss. N/A loses the most correct, like 3% Turbos also will lose some but It’s more like 1% per 1000ft They may be able to hold boost level but the air is simply not as dense so there will still be some power loss.
Easy fix is to change a pulley to make up for the loss in ambient pressure and your boost will be back, but then you’ll be adding heat by spinning it quicker.
Move back to sea level
