As to why that caused timing to be pulled, I don't know, but it did.
The 335i is a map based system. I am not concerned about the miniscule boost leak to be honest. IAT rising does have anything to do with the boost leak. It only rises with meth on, but even with meth off the boost leak is there.
I am trying to turn down the flow with no reported success (sensor shows pretty much the same flow with the port almost completely closed. I am diagnosing this now since I have sensor issues. What do you guys use for flow control valves?

Im pretty sure its the same flow valve you have. I want you to try something! take the check valve out from the tank, this means the tank will only be under pressure when you turbo is producing positive boost. This will likely help prevent the the sudden spike in flow pressure which could be the reason behind your problems. also make sure your flow sensor is after the solenoid and on the liquid side of the nozzle.
