* “With Monte” figures are estimates calculated from manufacturer ratings, not measurements. Results vary by vehicle, engine condition, fuel, climate and driving; individual results may be lower.

Why results vary

Estimated from the factory figures for this engine — not a measurement of your car. Real-world gains may be less or more, depending on a large number of contributing factors: displacement, aspiration, fuel, altitude, the condition of the engine and how the car is driven.

Results as reported by the owners. Experiences vary by vehicle, driving conditions, and selected mode.

“Noticed a huge improvement in acceleration, negligable increase in feel consumption.”

Halfway through the calibrating for Sport 2 mode, pretty satisfied so far. Noticed a huge improvement in acceleration, negligable increase in feel consumption. Haven't tried feel saver yet, good chance I may never try it as the sport 2 mode is a lot of fun and had way less negative impact on feul than I anticipated

“A gain of about 20 hp on a Kia Stinger GT.”

Translated from French

I tried this chip without any expectations. A gain of about 20 hp on a Kia Stinger GT. Power comes in faster, with a better kick on gear changes. I noticed the difference after about 50 km... I finished the 200 km on Race Max and I'm very satisfied. I recommend it.

Original: J'ai tenté l'essaie de cette chip, sans avoir aucune attente. Un gain d'environ 20hp pour un kia stinger gt. Puissance arrive plus vite et meilleur kick lors de changement de vitesse. J'ai remarqué la différence après environ 50 km... j'ai terminer les 200km à race max et très satisfait. Je recommande

“This tuning chip has made a very nice and definitely noticeable difference in the throttle response as well as top end before gear changes, plus an almost 40 more ponies to play with!!!!”

This tuning chip has made a very nice and definitely noticeable difference in the throttle response as well as top end before gear changes, plus an almost 40 more ponies to play with!!!! I would definitely recommend this if you’re looking for a little more get up and go at a reasonable price! I haven’t tried the gas saving feature yet so I’ll come back to you in a few months when the weather gets colder. I’m just enjoying the extra get up and go right now while the weather is nice. Setup was also very easy and went without a problem.

Frequently asked questions

64 Audi models from 1996 to 2026 — the A3, A4, A5, A6, Q5, Q7 and S models. Monte plugs into the OBD-II port. Pick your model above to see the exact engines and years we calibrate.
Look for one calibrated for your exact engine and year that you can unplug any time. Monte carries a calibration for each Audi engine and year listed on this page: it adjusts fuelling and ignition timing (and boost on turbo engines), and unplugging it returns the car to stock. Pick your model above to see the factory rating and our estimate with Monte.
The old “chips” that only fooled a sensor gave little or nothing. Monte is a calibration for your specific engine that changes fuel delivery and ignition timing. The figures on this page are estimates from factory ratings; our dyno results are in the Real Results block below.
The 2021–2023 A4 2.0 TFSI (201 hp, 236 lb-ft) gets about +32 hp and +38 lb-ft.
The 2018–2020 Q5 and 2014–2018 A6 2.0 turbo (252 hp, 273 lb-ft) get up to +34 hp and +39 lb-ft. Newer mild-hybrid versions gain a smaller share: about +26 hp.
Yes. The 2017–2019 Q7 3.0 supercharged V6 (333 hp, 325 lb-ft) gets up to +34 hp and +39 lb-ft.
No. Monte works in the engine computer’s temporary memory and does not rewrite its permanent memory. Unplug it and the car is back to stock.
Both carry the same calibration for your engine. Monte GT is set up and switched from the Monte app on your phone. Monte GTR adds its own touch screen with live gauges, a code reader, a 0–60 timer and a virtual dyno.
