wow - things are getting interesting. I swear like a trooper when speaking but struggle to see why you need to use it when writing!!!!
for what its worth - I've listened to your video postie thing from two posts ago - 3 times, an I can hear nothing that would worry me an I've got 3 smlblk chev powered cars on the road. when you button off, the exhaust note changes but i'd put that down to the exhaust not the engine.
just my unpolitical 2cents worth.
