Porsche Cayenne TDI 3.0L Performance Tune (2013–2016) — Q-PRO+ OBD Flash | KermaTDI

What it is
This is a Kerma performance tune for the Porsche Cayenne 3.0L TDI, model years 2013–2016. Unlike the equivalent VW Touareg and Audi Q7 tunes on the same 3.0L platform, the Cayenne TDI's model years don't include any that require bench tuning — all covered years flash via the Q-PRO+ programmer over OBD.

Performance gains

• +50 whp, +80 wtq (dyno-measured at the wheels, not crank)
• Up to 10% MPG improvement on long-distance driving, tested after the VW emissions fix
• Improved throttle response and reduced turbo lag
• More power delivered in the mid and top RPM range
• Uses stock hardware — no supporting mods required

How it's installed
Flash via the Q-PRO+ module over the OBD port — no mechanic visit or ECU removal needed. Price includes both the tuning and the Q-PRO+ module itself.

Software requirement
A Windows-based computer is required to email your stock ECU file to KermaTDI and receive the tuned file back. This is separate from Mac-incompatibility on the Q-PRO+ programmer itself — you need Windows for the file exchange step regardless.

The Q-PRO+ programmer
Stores both stock and tuned maps — switch back to stock before a dealer visit, then re-flash the tune afterward.

Requirements and limitations

• Requires the vehicle's stock emissions system to be intact. Will not function correctly with a modified or removed emissions system.
• Vehicle year/model must be specified at checkout.

Fitment
2013–2016 Porsche Cayenne, 3.0L TDI engine.

Common questions

Does my Cayenne need bench tuning, like some early Touareg/Q7 model years do? No — all Cayenne TDI years covered by this tune (2013–2016) flash via Q-PRO+ over OBD. The bench-tuning requirement on the Touareg/Q7 only applies to their earlier 2009–2010 model years, which the Cayenne TDI didn't have.

Do I need a Windows computer for this? Yes, for two separate reasons: the Q-PRO+ software itself is Windows-only, and you also need Windows to email your stock file to KermaTDI and receive the tuned file back.

Will this tune work if my emissions equipment has been removed? No, it's built for the stock emissions configuration.

Is the power gain measured at the wheels or the crank? At the wheels (dyno) — 50whp/80wtq.
