Thanks my friend. Since I plan to get the tune if anyone wants a valve controller send me a message - OAP deletes and Street headers going on tomorrow.

Scott @ softronics is an awesome guy and I had his tune on my now sold 997S and the car ran flawlessly but as tempted as I am putting his tune of my new GTS 4.0, I am not brave enough to void the warranty just yet, maybe in a couple of years

Full SOUL System installed today. Race headers w/out cats, OAP’s, and VALVED Exhaust.
Currently in full open mode, this is the dream set up in my opinion. A proper GT car now. It snarls, pops, burbles, whales, and screams. And it does all this on demand. With gentle throttle, (still full open), I can drive it next to a police car with no concern. It only screams when you want it too. The VALVED exhaust really does it’s job. Now, it does awesome sounds on down shifts with auto blip on. And start-up is a sonic boom of awesomeness.

- 200rpm increase
- Turn off Cylinder Deactivation
- Turn off Auto Start/Stop
- Keep Valves Open With PSE Button Pressed
1. Does the redline increase of 200rpm also increase the rpms at which Porsche records engine overrevs? (Side question: does anyone know what the default overrev ranges are for the 4.0 engine in the GTS cars? I've read conflicting opinions here, but I'm assuming the factory Range 1 rev counter range is 7800 - 8000rpms.)
2. For those of us too chicken to do a full ECU tune, you should consider offering a $695 option that simply does those last three bullets: Turn off Cylinder Deactivation, Turn off Auto Start/Stop, and Keep the Exhaust Valves Open With PSE Button Pressed!

Doing it in the ECU is more elegant than adding a separate exhaust valve controller module with extra hardware and a separate remote control to operate it.

Maybe also a $495 option for just keeping exhaust valves always open with PSE pressed, and nothing else. Would still impact warranty while these cars are young, but that would be good for people who want to keep the engine operating within stock parameters and keep *** and cylinder deactivation.

1. PSE valves open fulltime when PSE activated; stock operation when PSE disabled (i.e. valves open at 5K rpm)
2. Auto S/S disabled on ignition, but keep cylinder deactivation when Auto-S/S enabled. (some say this can be done with PIWIS as well).
Regarding (2) above, I'm almost never going to use Auto S/S. The only time I would use it would be a long highway drive where I might want a bit more fuel economy for a long trip.
Subsequently, I might also do the "full tune" when factory warranty is over (4 years) and/or if I do sport cats... decisions, decisions ....

Sending my ECU in very soon after 2nd dyno run with exhaust. My note when I ship it will just say: Program ECU to WIN!

I appreciate SOUL being accessible and ready to answer questions from customers. I do have a question about the SOUL valved exhaust.
Is the diameter of the piping in the closed valve paths big enough to support sufficient airflow to allow the engine to run normally (without the ECU pulling timing) with the valves closed say up to 5,000 rpm ?
I am thinking of a scenario where I could use the 3rd mode of the CG controller to keep the valves closed in all RPM when I am just putting around town under the radar......
