Mercedes ML450 Hybrid tune.
The 2010–2011 Mercedes ML450 Hybrid 3.5L V6 is rated 335 hp and 381 lb-ft combined from the factory; with Monte the estimate is up to +34 hp and +38 lb-ft. On a hybrid the gain is a smaller share of the combined output.

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.

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.

Installed the Monte GTR on my 2023 Silverado and immediately felt the difference — faster throttle response, smoother shifts, and more power through the mid-range. The built-in display is a great bonus; I can see real-time data and even run quick dyno tests. Super easy to use and can go back to stock anytime.

“Throttle response is instant, acceleration feels stronger, and the truck runs smoother overall.”
Installed the Monte GTR on my 2022 Ford F-150 5.0L V8, and I’m seriously impressed. Throttle response is instant, acceleration feels stronger, and the truck runs smoother overall. The built-in screen makes it easy to monitor performance data on the go. Super simple plug-and-play install, and I like that I can return to stock anytime. Great upgrade for anyone wanting real, noticeable gains without complicated tuning.

“I wasn’t expecting such a difference, but the car now drives smoother and feels more responsive, especially during long highway trips.”
I installed the Monte GTR on my 2023 Land Rover Defender 2.0T here in Guangzhou. I wasn’t expecting such a difference, but the car now drives smoother and feels more responsive, especially during long highway trips. The screen looks high-end and matches the interior perfectly — it almost feels like it came with the car. Setup took just a few minutes, and I like that it doesn’t change anything permanently. Overall, a smart upgrade that really complements the Defender’s power and comfort.

Monte Tuning is compatible with Mercedes ML450 Hybrid
Mercedes ML450 Hybrid tuner: how it works
Monte plugs into the OBD-II port and carries a calibration for your engine. It changes fuel delivery and ignition timing values in the engine computer’s temporary memory, at up to 256 load points, and does not rewrite its permanent memory. Unplug it and the car is back to stock.
What ECU tuning adds on a Mercedes ML450 Hybrid
Turbo engines gain the most, because a calibration can raise boost — up to 20% more power. Naturally aspirated engines gain up to 12%. The table above shows the factory figures and our estimate for each engine and year. Estimates are not a measurement of your car: fuel quality, altitude and the condition of the engine all move the result.
Monte GT or Monte GTR
Both carry the same calibration. The GT is controlled from the Monte app on your phone. The GTR has its own touch screen with live gauges, a fault-code scanner, a 0–60 timer and a virtual dyno. Both have an Eco mode for mileage, and both move with you to your next car.
