Volkswagen Tiguan R Stage 1 & Stage 2 Tuning

The Volkswagen Tiguan R combines everyday practicality with serious performance potential – and at our Slough performance tuning workshop, we can unlock every bit of that hidden power. Our Stage 1 and Stage 2 ECU remapping is tailored to extract maximum performance while maintaining reliability, whether you want sharper throttle response, stronger acceleration, or an even more aggressive character.

Our Stage 1 tuning is perfect for those who want a substantial performance increase without changing any hardware. By optimising the ECU’s boost pressure, ignition, fuelling, and torque management maps, we deliver smooth yet explosive power gains, transforming the Tiguan R into a faster, more responsive SUV while keeping it comfortable for daily use.

For drivers looking for the next level, our Stage 2 ECU remap adds supporting hardware upgrades such as high-flow downpipes, upgraded intercoolers, and performance intake systems. This allows the engine to breathe more efficiently, run cooler, and produce even more power and torque, all while maintaining the dependability you expect from a Volkswagen.

 Trustindex verifies that the original source of the review is Google. Brought my Audi S3 in for a Stage 3 tune with a bigger turbo and full supporting mods. Things didn’t start smoothly — the Falcon turbo I had fitted from eBay turned out to be faulty and smoked heavily on the dyno.Instead of rushing the job or giving me attitude, they helped me swap it out for a proper Garrett PowerMax and carried on professionally. Then I ran into fueling problems caused by another low‑quality eBay part, and again they took their time, diagnosed the issue properly, fixed it, and made sure everything was right before continuing.After all the setbacks, they still mapped the car, spent a lot of time on it, and didn’t charge me anywhere near what the work was worth.They showed patience, honesty, and real skill. Very happy with the service and the way they looked after me.

 Trustindex verifies that the original source of the review is Google. This is the second time I have used Onyx Performance first time for wheel refurbishment and last time for remap and i would use their services again in the future without a doubt. They are very knowledgeable about what they specialise in, they are polite and you can see they care not only about what their customers want to do but also about what they can offer the customer. Thanks to the OP team.

 Trustindex verifies that the original source of the review is Google. Took my Mercedes C200 to Onyx performance for a stage 1 remap, my car is much quicker and throttle response is much better than before the remap. They also advise you about power and gains and the maps are tailored for your specific car and model, no stress on engine or gearbox. Thank Onyx , Brilliant work.
