hey im in the same boat, took my car to turbo tune bout 6months back, i hav a fmic, hks cat back, walbro 500hp pump, pod filter and running 11psi flat (earthed out solenoid). My car got a read out of 221.1rwkw. My engine is a bit weird tho you cant run the pod straight off the airflow meter cause my car will just flood up wen hitting boost. i need an extra bit of pipe on the end and then it runs sweet, turbo tune said they hav never encountered a problem like that
