Product Description
Porsche's official name for the 992 Carrera's 3.0-liter twin-turbo six, the "9A2 Evo," tells you exactly how seriously this engine was developed: a genuine evolution of the acclaimed 991.2 engine, sharing the same block, bore, and stroke, then refined further with a revised cast-iron exhaust manifold, larger symmetrical turbochargers with electric wastegates, compression raised to 10.2:1, and intercoolers moved on top of the engine for a dramatically shorter intake path. This is Porsche sweating every detail of an engine it already knew was good, and those refinements carry across the Carrera S, GTS, and Targa variants this engine powers too.
Weistec's calibration works within that refined factory architecture, extracting more from the improved turbos and intake path through pure software recalibration, validated to the same standard as Porsche's own engineering while knock protection, thermal management, and OEM diagnostics stay exactly as the factory built them. Across this platform the gain is substantial (on the order of 120 hp and 180 lb-ft over stock), real proof of how much headroom the 9A2 Evo's larger turbos left on the table, ready to be unlocked.

Complete The Upgrade
An ECU tune alone won't remove all factory limits or fix how power reaches the ground. Add these to round out the upgrade with no limitations.

What is a CPC module?
The CPC (Central Powertrain Control) is a separate control unit that manages things like the active exhaust valves, radiator fan, intercooler pumps, and speed limiter. On many newer Mercedes-Benz vehicles, it also houses torque limiters that can hold back an ECU tune from reaching its full potential.
What is a TCU tune?
A TCU (transmission control unit) tune delivers faster, firmer shifts with higher line pressure, reducing clutch slip and increasing the transmission's torque capacity. It's a worthwhile upgrade on its own, or paired with an ECU tune for a fully sorted powertrain.
Good to Know
- This is a reflash of your original module, not a stand-alone unit.
- Power gains vary by vehicle, modifications, fuel, and operating conditions (ambient temperature, altitude, etc.).
- New or upgraded spark plugs are always recommended when tuning.
- Product may not be emissions compliant. Check local laws prior to installation.
- Always use a battery charger during programming.
