Revs erratically


sounds like the rev limiter is kicking in to keep the engine from over rev damage, there should be a way to get the limiter disabled or perhaps get the turbo building boost sooner.

What does the diagnostic code P2181 mean on a Subaru Impreza WRX?


this is a coolant performance code. Usuallly sets this code if the connector was left unhooked to the coolant sensor or the thremostat is stuck open. By any chance do you have a gauge that seems to be on the cold side ??
