Product Description
The 997.1 Turbo's 3.6-liter twin-turbo flat-six carries genuine motorsport DNA. It's a direct descendant of Porsche's legendary Mezger architecture, built around a dry-sumped, race-proven bottom end that traces its lineage through the GT1 program all the way back to the 962 and 935. It's also a genuine engineering first: the introduction of variable-turbine-geometry turbochargers to a gasoline production car, virtually eliminating the lag that had defined earlier 911 Turbos. Factory output was 480 hp, delivered by an engine whose racing pedigree left it with plenty more to give.
Weistec's tune for the 997.1 is a software-only recalibration that works with that VTG hardware, refining boost and timing curves to OEM levels of precision while keeping every factory safeguard (knock protection, thermal limits, OEM diagnostics) exactly as Porsche built it. The result is a significant, verified gain of roughly 75 hp and 85 lb-ft, extracted from a racing-grade bottom end that was built to handle exactly this kind of work and rewards it in full.

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.
