        95 Octane in NZ is way way wya ywyay ywy ayy yaywywayyawy too low to be running 23psi of boost

        you need to run 98 Octane and a octane booster and retarted timing if your going to run that higher boost

            some ppls say that the GTR has a "fuel cut/Boost cut" @ 23psi
            others say it doesnt have a cut and just dumps the injectors to max when the voltage form the AFM gets too low

            either way, the AFM is not ever ment to send a " 0 volt" signal to the ECU..0 volt = fuel cut, hence the RX7/GTR AFM are ment to get around this for the BP26 ECU

            my guess is you have a air leak/pressure leak at that boost level, or something like the Knock sensor telling the ECU somethings wrong so its triggering a warning ..im not sure about the GTR's way of safe guarding the engine

              The only thing that trigger the buzzes is the boost cut, 23 psi is alot for a gtr on the stock fuel management, the best way to get rid of it would be to lower the boost a couple of psi or swap for a stand alone engine management. try lower the boost a couple of psi if you no longer have problems with the buzzer, you was hitting the boost cut. Typically at high boost levels the wastegate port needs to be enlarger to keep the boost under control (no boost spike)

                hey there the fuel management keeps up well it was a leaking bov in the end the ecu was thinking a hose blew off and kept retarding the timeing and buzzing for boost cut ive since sorted it and it runs alloy better now, and with the turbo your right about the wastegate however i dont mind too much as i just change when it hits 17psi thanks for the advice and if u like my gtr dont foget to vote for it in ride of the month thanks
