I know the Reflex is all the rage with the N54 guys but is anyone successfully using it on the newer N55 platform? I recently began the tuning process on my M235 which has a custom big turbo (BW8474) and port injection, twin Walbro 450's etc. my tuner is advising against PI on anything other than 93-95 pump, anyone have any thoughts or experience on this?
