Porsche Cayenne Turbo S (958) ECU Tune

Product Description

The Turbo S runs the same 4.8-liter twin-turbo V8 as the standard 958 Cayenne Turbo, but it's Porsche's own harder-edged calibration of that engine, the factory's way of carving out a genuine performance gap for its range-topping Cayenne trim. It's Porsche pushing its twin-turbo V8 architecture right up against what it considered the safe ceiling for a full-size SUV at the time, and doing it with nothing but calibration expertise.

That aggressive factory starting point means Weistec's ECU tune for the Turbo S is an even more finely targeted piece of software recalibration, built entirely on top of Porsche's own engineering with every knock-protection and thermal safeguard left exactly where the factory put it. It's validated to the same standard as an OEM calibration, not a shortcut aftermarket flash, and even starting from that already-elevated factory baseline, it finds a further 40 horsepower and about 88 lb-ft of torque still hiding in the hardware.
