“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.

“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.”

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.
