GTS calibrations are developed for vehicles with all factory emissions equipment intact and functional. Features that remove or raise factory speed and rev limits are intended for closed-course use only. These calibrations are not CARB-certified, and the customer is responsible for compliance with all applicable laws, including the emissions and inspection requirements of their jurisdiction.
The GTS difference: a real tune built for your exact car, not one calibration with three names on a dropdown. We’ve got the injectors and turbo kits to back it up, and the in-house support to actually run it. Tuning VW, Audi & Porsche since 2010.

What Stage 2 does
23 psi on the factory K04-02x takes a stock 225 hp car to 285 hp and 300 lb-ft. Built for 93 octane / 98 RON, it adapts to 91 / 95. Lag removed, speed limiter removed, rev limit raised to 7000.
What you need on the car
- Required: an upgraded exhaust and a 4-bar fuel pressure regulator.
- Recommended: upgraded diverter valve, upgraded intercooler.
After you order
- Order. 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".
- 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.
- Flash. We build the calibration for your engine code, 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.
- Log. Drive, log, send. If anything wants adjusting we adjust it and you flash again. Revisions usually come back the same day, and within 72 hours at the outside.
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
- Launch Control: "Soft (No pops)" is included free. "Hard (2 Step/Antilag)" is an add-on, for off-road and competition use. Pick "None" if you do not want it.
- No-lift shift: included free with every GTS tune.
- Mail or Remote Tuning: "I want the Remote Tuning Service" if you need the cable. "I already have a GTS Remote Tuning cable" if you have tuned with us before. "Mail Service (Canada/USA)" to mail the ECU in. "Dealer" if a shop is doing the install for you, and we deal with them directly.
- Pops and Bangs: exhaust crackle on lift-off.
- Hard Cut Rev Limiter: a hard fuel cut at the rev limit instead of the factory soft limiter.
- IMMO / Immobilizer delete: removes the immobilizer check so a swapped or spare ECU runs without the key and cluster handshake.
- Spare ECU: we supply a tuned ECU so your original stays untouched on the shelf.

Why GTS
Tuning since 2010, as Gonzo Tuning first and as GTS since 2013. Every calibration is written in house and the flashing tool is ours, not a rebadged package, and we never ask for remote access to your computer. Your original calibration is kept, so the car can go back to stock whenever you want it to. Reflashes carry a one-year warranty, and if you are not happy within 30 days you can go back to stock for a refund under our return policy. Support in English and Spanish.
Ordering from Canada or overseas
Canadian owners have ordered from us since 2014 and Canada is our second-largest market. The tune is delivered digitally, the cable is delivered within Canada with no customs and no import fees, we accept Canadian cards, and return shipping on a mail-in ECU is free. Anywhere else in the world, remote tuning needs the car, the cable and an internet connection, nothing else. We have tuned cars in Australia, Germany, the United Kingdom, the Netherlands, New Zealand, Hungary, Puerto Rico, Panama, Costa Rica and Barbados.
