That’s interesting you keep getting a CEL, I’ve had the blackhart for over a year with no issues. I would definitely be looking at the valves.

I don’t know if the shop could have broken them it’s only 3 bolts or didn’t install them back the right way

Why not take it back to the shop and get it up for a relatively easy check of everything they've touched... or, may have?

Have them check them out. Verify they are plugged in. Worst case you can have the code deleted.
