Stage 2 tuning is where things get really exciting. It’s all about boosting the power and performance of your M140i. But to make it happen, there are a few essential upgrades required.

1. Stage 2 Custom Engine & XHP Gearbox Software:
- This is the heart of your Stage 2 transformation. Custom software is tailored to your M140i, optimising engine and gearbox performance.
2. Downpipe Or High Flow Sports Catalyst:
- Upgrading your downpipe or adding a high-flow sports catalyst is crucial. It allows for improved exhaust flow, which directly impacts power and efficiency.
3. OPF Delete:
On newer models with OPFs (Gasoline Particulate Filters) or PPFs (Petrol Particulate Filters), removal is essential. This enhances exhaust flow and power.
4. Induction Kit:
- A performance induction kit ensures your engine gets the air it needs for optimum power.
5. Race Spark Plugs:
- High-performance spark plugs are key to igniting the extra fuel and air, resulting in more power.
6. Upgraded Charge Pipe:
- An upgraded charge pipe improves airflow, contributing to overall performance.
7. (Optional) HPFP Upgrade:
- While optional, a High-Pressure Fuel Pump (HPFP) upgrade can provide more consistent fuel delivery, supporting higher power levels.

If you’re ready to enhance your M140i’s power, performance, and overall driving experience, get in touch with us today. We’ll help you build the perfect Stage 2 package, ensuring your BMW M140i is primed for a high-performance adventure.
You’re considering a Stage 2 remap for your BMW M140i, and you’re likely wondering if it’s worth it. Let’s dive into the details. A Stage 2 remap is a significant step in optimising your car’s performance. Here’s why it’s worth considering:
1. Power and Torque Boost:
Stage 2 remapping isn’t just a minor tweak. It’s a substantial upgrade that significantly increases your car’s power and torque. For an M140i, this can mean an extra 50 horsepower or more.
2. Enhanced Performance:
The extra power translates to enhanced performance. Your car will accelerate more rapidly, making overtaking and spirited driving a pure joy.
3. Improved Responsiveness:
With the remap, you’ll notice improved throttle response. The car becomes more eager to do your bidding, making for a more engaging driving experience.
4. Thrilling Sound:
It’s worth noting that with a Stage 2 remap, a high-flow exhaust system is typically part of the package. While this improves performance, it can also make your car louder. If you enjoy the sound of a sportier exhaust, this is a bonus.
5. Customisation:
One of the great things about remaps is their versatility. You can often choose different settings based on your preferences. So, if you’re not looking for an overly loud car, you can still find a balance that suits you.
However, it’s also essential to consider your personal preferences and driving style. If you’re not a fan of a louder car or if you primarily use your BMW M140i for daily commuting, you might want to explore other options.
In conclusion, a Stage 2 remap is definitely worth it if you’re looking to extract more power and performance from your BMW M140i. It’s a thrilling upgrade that can turn your already excellent car into a high-performance machine. To see if it’s the right choice for you, don’t hesitate to get in touch with Onyx Performance.
