Do you have boost gauge? If yes does it show any boost?
Make sure all the hoses replaced were same diameter. most were 3 and 4mm. If too big and leaking at connectors the n75 wont work and it will let the WG open at its spring rate. Does it feel like it has some cause stock spring on WG will still push 5 not much but some? may have also knocked some other hose loose. Maybe the 90 degree turbo hose on top of turbo going to hardpipe happens a lot.
Check all the power connectors on the 2 valves you were working on. you may have snapped the wire in the harness causing them to not work but that usually causes CEL.
