Ask the shop
What does Stevenson Tuning offer?

Custom ECU tune files, DSG tunes, Powergate flashing hardware and 304L stainless exhaust and delete kits for diesel VW, Audi, BMW, Porsche and Range Rover.

What is custom tuning and why does it matter?

A custom tune rewrites the parameters in your engine control unit for your exact engine code and setup. Done right it adds power and torque while keeping the car reliable. Generic files are written for the average car. Ours are written for yours.

What is the difference between Eco, Stage 1, Stage 2 and Race?

Eco files are for deleted cars that want MPG back. Stage 1 is the most power on a stock car with no supporting mods. Stage 2 needs an exhaust kit and, on DSG cars, a clutch or DSG tune to hold the torque. Race files are for track use with the full supporting package.

Do you tune race cars?

Yes. Track and race setups are written per car. Email the shop with your build sheet.

Do I need a shop to install the tune?

No. The Powergate pairs with your phone over Bluetooth and flashes in your driveway. You need a stable Wi-Fi connection or a phone hotspot during setup.

How do the exhaust kits fit?

Bolt on with CNC V-band flanges and lapped connections. 304L stainless, orbital TIG welded. Most owners install with hand tools in an afternoon.

Why two shipments?

Pipes are boxed in the shop. The Powergate ships from the tuning bench once your file is written. You will get two tracking numbers.

Do you ship to the USA? What about duties?

Every day. Duties, taxes and tariffs are the buyer's responsibility. All products are sold for off-road use only.
