M-Engineering: PSE Valve mod for 992 Carrera - NEW VIDEO
Shoutout to our media master Kris for getting this video done for us on a gorgeous Lizard Green 992 C2S that came in to our South Florida HQ for a Stage 2 calibration with our PSE valve mode and free-revving in N. The sound this car makes now is how it should have been from the factory!
This is a Stage 2 992 Carrera S with the M-Engineering M-Tuner Calibration Suite.
As you may or may not know, the 992 platform has exhaust valves that open or close more depending on what mode you are in or if you push the "exhaust" button on your dash. However, the valves still open partially and it's not until higher RPM's at WOT do they fully open. With M-Tuner and our PSE Valve mod, we can force the valves open 100% of the way when you're in Sport or Sport +, or when you push the exhaust button. It is open at all times including idle. Check this video out to see how it sounds! In Normal Mode, the PSE functions as it did when stock.
This mod is a FREE add-on for all M-Tuner owners on the 992 platform. It is also good for about 10 to 12whp just by forcing valves open.
Even if your car does not have the expensive factory PSE add-on, we can flash the PSE valve mod to the car so when you move between normal and the sport modes, the valves still open all the way up.

I have a variant of this mod from M: in Sport mode the PSE valves open 50% by 3700 and 100% by 4500. To me this a 'best of both worlds' approach and avoids unpleasant / gratuitous low rpm drone but really sings up top. IMHO this is they way it should have come from the factory - so much so I'm no longer considering an aftermarket exhaust (at this time) for my 'daily driver'. My tune also disabled the cold-start noise to avoid waking the neighbors early in the morning. The guys at M have been really great to work with - recommended.

>> how does it compare to 100% open?
At less than 3750 it sounds like the factory 'sport' mode, over 4500 the valves are 100% open and gives a *much* improved sound both in tone and volume. IMHO the '100% open all the time' option is extremely unpleasant / drone-y at low RPM's - the only reason I can think of to go with 100% open is for bragging rights at C&C meetups where you are doing stand-still revs like in the video, but in actual use I found it extremely unpleasant, so I am now very happy with the compromise.
(Full disclosure that preference in exhaust sounds is hugely subjective - one person's drone might be another's beautiful music. The good news is that with the M tune we've got options).

It's all personal preference with exhaust, some guys want the full enchilada and some do not. We can happily make some adjustments to opening RPM although most guys tend to just stick with 100% open all of the time as it gives you a huge bump in volume and modest power increase.

PDK. Yep, in 'sport mode' went from '100% open all the time' to '100% open starting at 4500rpm' (valves begin opening at 3750 for a smooth transition by 4500). For me it's a perfect compromise between mild-mannered around town to hooning in the canyons.

Valves open 100% + raised stationary rev limiter are great options on the M Engineering tune.
As for how obnoxious it is for valves to be open and whether it drones, everybody has their own tastes. I don't find the car to drone at all with valves 100% open in sport and sport+ all the time. It is still relatively quiet compared to many aftermarket exhausts I've had that delete secondary cats and resonators but retain the main stock cats. I personally also don't notice any droning at all at any speed. The whole point of modding the exhaust either with exhaust valve programming or an aftermarket exhaust system or various high flow cats or straight pipes, etc. is to make it louder. Droning, to me, is the super unpleasant harmonic noise I've heard in my friend's various V8 muscle cars where the exhaust hits a certain RPM and it sounds like this loud, numb, droning sound in the middle of your skull. To me, the 100% valves open mod on the 992 just sounds like a louder stock exhaust. It's still exceptionally tame and mild compared to most exhausts on naturally aspirated cars which are way louder than turbocharged cars.
One cool thing is when I start the car and I turn the dial to sport or sport+ and valves fully open, there is a subtle but noticeable vibration that permeates the car. It adds another dimension to the car that makes it sportier and more motorsport feeling.
I'm not discounting jlegelis's opinion, just bringing a different perspective. I've modded almost every single exhaust on every car I've ever owned. If you come from a modding background like me, valves open 100% is not loud at all. Just sportier sounding than stock. I think it's a testament to M Engineering that they are willing to accomodate our specific requests. The tune is pricey but it is worth every penny due to the outstanding customer service and the free updates and tweaks to your tune preferences, tune stages, etc.
Also cold start delete is awesome... and the added 90-100 or so hp isn't too shabby either.

Oh man, that's such a better option than trying to get a dealer to do the programming and figuring out how to retrofit the PSE button on the dash. Hmmm, sounds like I need an M-E tune sooner than I thought!

I have a C2 without PSE. I installed a Soul valved exhaust and my car only has a Sport button. Would your tune do anything for me in this configuration? My dealer said they could not turn PSE on in the programing.
