skyking - Do you mean http://forums.rennlist.com/rennforums/997-forum/496638-997-2-pse-pics-and-short-review.html ?? If so Im not sure where he gives anything definate on switching 'on' via the dash button being really 'on' all the time. Gen1 had its own button if you didnt have chrono but it still muted the sound between 30-50mph to meet noise regs, exactly the same as for those with chrono who activated PSE via the sport button instead. Some people thought 'on' via the relevant button meant it was full on all the time... however if u unplugged it then it truely was on all the time and was significantly louder between 30-50 than with it 'on' but still plugged in. Sportchrono sport button or seperate PSE button made no difference here, both were much louder when unplugged. I suspect the same will be true on gen2 PSE too for the same reasons - to meet noise regs, and more to the point because it can due to the fact it clearly has variable baffles to enable the switching on and off!
John - I do take onboard the vaccum hose -v- unpluggin comments though but these indicate to me in principle that once again 997.2 PSE will mute the sound midrange and therefore . Again on gen1 when it first came out lots of people suggested the vaccum route as preference over the unpluggin but in time both became accepted as equally effective solutions.
Until we hear first hand from a member who has tried it on his/her own car then everything it still just speculation - hence why im asking above for anyone with first hand experience of trying to unplug a gen2 PSE for themselves.
Cant believe none of the forum Gen2 PSE owners here have yet tried unplugging, it was such a huge sound improvement on Gen1 PSE. Hopefully I will have mine within a couple of weeks (whenever I finally get my dealer to confirm the parts are available for retrofit in the UK) and I will certainly be unplugging mine on the first day if it is at all possible! Come on guys, dont be slacking here and letting me get a world first!
