Powergate 4

Flash your tune from your phone

The Powergate pairs over Bluetooth, reads your ECU and loads your Stevenson tune file from the cloud. Switch between stock, eco and stage files whenever you want.

  • More power

    Stage 1 adds up to 30 hp and 65 lb-ft on a stock 2.0 TDI. Stage 2 adds 55 hp and 95 lb-ft with supporting mods.

  • Better mileage

    Eco files are built for deleted cars that want MPG back without losing drivability.

  • Flash in your driveway

    Pair the Powergate over Bluetooth and flash the file in your driveway from your phone.

  • Backed by the shop

    Every file is written in house. Email us the serial on the back of your Powergate and we sort it.

Pipe is quality made and easy to install once you remove all of the old stuff. Tune seems to be working as it should.

Ask a question
Do I need a shop to install the tune?

No. The Powergate pairs with your phone over Bluetooth and flashes the file in your driveway. Pipes are bolt on with a V-band flange, and most owners install them with hand tools in an afternoon.

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

Eco files are for deleted cars that want mileage back. Stage 1 is the most power you can run 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.

Why do tuning and pipes ship separately?

Pipes are built and boxed in the shop. The Powergate ships from our tuning bench once your file is written. Expect two tracking numbers.

Do you ship to the USA?

Every day, from Vancouver. Duties, taxes and tariffs are the buyer's responsibility, and every product is sold for off-road use only.

Do you offer dealer pricing?

Yes. Register through the dealer portal and we will set up your account.
