Chemically speaking, there's no particular reason that a turbo, blower, or happygas shouldn't pass emissions - it's just because it's an "unauthorised modification" that it won't pass. CalEPA and CARB are real pains about this - for no good reason I've been able to uncover.
If they did the thing properly, they wouldn't have a visual check - which is nonsense - and just do the sniffer. Pass, you pass. Fail, you find out why. Don't even need to lift the hood for that...
As far as the "chassis dyno" - it's more properly called a "treadmill" - it's not done to measure power output, just to "load" the engine to get a better picture of on-road emissions. Since it's an "axle dyno" (only one end,) vehicles supplied as or converted to AWD can't be run on it, and still use the older "idle test" (which is easier - hint, hint.)
