Friendly bump since this thread has some good info and also my results:
SUPER easy while doing an inlet install
Both wastegates took 10 seconds each to get on and had plenty of room for hands and to route how I liked, the boost solenoids were honestly tougher. I used this CRP 3.5mm BMW blue silicone hose from FCP.

Also have the ECS vacuum relocation kit on the intake side and all new black hosing that's tucked out of sight.
