Looking at the manual and videos found in the forum, I assume there should be a clear change in the RPM?
Take the intake off and run it, this check is very important, you will be going around in circles if there is air causing these issues.
While running there might be some very small bubbles, but the key indicator of a air leak is the line being clear after sitting over night.
Yes, the idle should fish bite, I think you need to bump the timing to the drivers side. About a dimes width then check again.
