Fits

They all run the same K04-064 turbo. The calibration is written for your engine code. Not sure which code you have? Find your engine code in two minutes.

Not this listing. Same badge, different engines. Go by the code, not the car:

The MK6 GTI moved to the EA888. The MK6 Golf R kept the EA113. MK7 and newer Golf R are in the EA888 Gen 3 guide.

What the tune does

Written for 93 octane / 98 RON and adapts to 91 / 95. Throttle response is sharper, the midrange fills in, and boost and timing are set for the fuel you actually run. Every stage: lag removed, speed limiter removed, rev limit raised to 7000, and better mileage when you are not in it.

The K04 cars came from the factory with uprated rods, revised pistons and a larger intercooler, so the gains are bigger than on the K03 cars. The long version is in the EA113 2.0T Tuning Guide.

Pick your stage

What you need on the car

• Stage 1: nothing.
• Stage 2: an upgraded exhaust. The calibration is built around the improved airflow, so do not run it on a stock car.
• Stage 2+: the Stage 2 parts plus the high-pressure fuel pump internals upgraded, for more boost and more timing. You do not need the pump for the Stage 1 and Stage 2 figures.

Before you tune

The EA113 weak spots, most important first:

• Rear cam chain tensioner: a rattle from the back of the engine on a cold start. Stop and fix it before anything else: if the chain jumps a tooth, this interference engine is done.
• Cam follower: a wear item on every EA113. Inspect it every 10,000 to 15,000 miles and replace it before it wears through, or the pump rides on the camshaft and you are buying a head.
• PCV: fails as a matter of routine. A failed one opens a vacuum leak or pressurizes the crankcase and pushes out the rear main seal.
• Diverter valve: the early diaphragm valves split and leak boost. The revised piston-style valve is a cheap part and a short job.
• Coils and plugs: fresh coils and correctly gapped plugs before you flash, one step colder past Stage 2.
• Carbon: no port injectors, so nothing washes the intake valves. Plan on a walnut blast every 60,000 to 80,000 miles.

Each item is covered in the EA113 2.0T Tuning Guide.

After you order

1. Order. Pick your stage, then choose Remote Tuning. A GTS cable ships with your order for a one-time $40 and it is yours to keep for every tune after this one. Already have one? Choose "I already have a GTS Remote Tuning cable".
2. Read. Plug the cable into the OBD port and a Windows laptop, Windows 10 or later. An Intel Mac on Boot Camp works too. Our software identifies your ECU and saves your original calibration before anything is written.
3. Flash. We build the calibration for your car, your hardware and your fuel. You get a message the moment it is ready, and you flash it yourself in your driveway in about ten minutes.
4. Log. Drive, log, send. If anything wants adjusting we adjust it and you flash again. Stage 2+ usually takes a revision or two to dial in for the exact hardware and fuel. Revisions usually come back the same day, and within 72 hours at the outside. If the car feels off after a flash, send us a log first: a split diverter valve, a failed PCV or tired coils look like a bad tune.

Prefer to mail the ECU in? Mail-in is free within the USA and Canada. We flash it on the bench and send it back in two to three days. Local? An OBD flash at the shop takes 10 to 15 minutes. How remote tuning works, start to finish.

Options explained

• Stage: pick from the table above.
• Hard Launch Control (2 Step): an add-on, for off-road and competition use.
