You wont here them just stationary reving the engine (neither do i) but i suspect as you have a 'louder' exhaust on your vehicle than standard, that may cloak the noise. I dont hear mine much either when i open the taps, a slight whistle but thats about it. Remember the turbo's cloak the noise of the 'true' flat 6 and your 'loud' exhaust is probably masking the turbo whistle. These cars arent Subaru's or EVO's with loud dump valves etc etc, these are refined cars........

Incidentally, are you hitting your boost pressure???

You're kidding right. I sure hope so. Do you understand how your turbos work? Your turbos will not produce boost when revving the engine at a stop...watch your boost gage next time.

Have someone else drive your car while you stand near the road... or drive in another car behind yours. The sound is behind you.

yes i know turbos wont spool at a dead stop but i see videos of guys just reving there engines and you can hear them but to answer your question of boost im getting 0.9 but i still need to recalibrate ecu for 1.1 but other then that im good to go

maybe it is my exuast it is loud should i go with diff exuast ? or should i put a diff air filter setup mine is still stock the guy who did my car said it was awaste of time so i left it stock plz help ty

I have the Europipe setup, and between 3000 and 5000 rpm, I can hear the turbos whistling....but the Europipe isn't really a loud system, I think WOT is 103db....so the comment about your exhaust system masking the sound could have merit. I'm running stock everything except Diverter Valves on an X50.
