I have removed the secondary air pump/EGR valve a little bit after I did the CSL headers install this summer and no CEL. Maybe because I already have a flash software with the ESS VT1-445

I think you should try Zstig, pretty sure you don't need a reflash with your ESS setup. Anyway, even if it throw a code, the car will still work fine.

And please don't pay for the VAC cover. DIY! It's super easy to do with a drill and a grinder with cutting disc. Just use a piece of 1/4'' SS flat bar and put some hi-temp silicone to do a gasket. Use the OEM nut that are already there to hold the flange the EGR valve and also use that flange to get the shape to cut. It will look like this in the end:
