The honest pitch
What this actually does to your Range Rover Sport SVR
The SVR's supercharged V8 is theatre on launch and a normal Range Rover at 30mph. The factory valve programming is largely to blame.
Open Valve pins the flaps wide and lets the supercharger whine and V8 bark come through the bumper at any speed.

Long read
The Land Rover Range Rover Sport SVR valve story
The L494 Range Rover Sport SVR pairs a supercharged 5.0 V8 with one of JLR's better-sounding exhaust systems and then quietens both with a conservative valve map. At launch in 2015 the cars sounded considerably more aggressive than the late-model facelift cars do — the valve programming and the silencer construction both shifted.
Open Valve pins both rear valves open. The supercharged V8 then sings the way it does on full launch in every mode. The supercharger whine becomes properly audible from outside because the exhaust isn't acoustically damping it.

Land Rover Range Rover Sport SVR — FAQ
Does it work on the SVR Carbon Edition?+
Yes — same actuator hardware.
What about the newer L461 Range Rover Sport SV?+
L461 SV uses different actuator — separate module in development.
Will it throw a warning light on the dash?+
No. The module sits in the signal path between the ECU and the actuator motor. The ECU sees a normal actuator response back, so there's nothing to flag. We've shipped thousands of these and not had a single check-engine call linked to the module itself.
Is it reversible?+
Yes, fully. Unplug the module, plug the OEM connectors back into each other, refit the trim — about three minutes' work. There's no permanent change to the car, no part cut, nothing in the ECU. Dealer service visits, MOT, sale to a new owner — pull it out and it's like it was never fitted.
Does it work with an aftermarket exhaust?+
If the aftermarket back-box retains the OEM-pattern valve actuators (most do — Akrapovic, Milltek, IPE, Capristo all run the factory motors), yes. If the system is a straight-through with no valves, there's nothing for the module to override.
Towing affected?+
No — full tow rating retained.
Off-road modes?+
Terrain Response, low range, locking diffs all unaffected.
