BMW X3M Competition 2024 3.0 510hp Dyno Test

In our latest dyno test we have this awesome 2024 F97 BMW X3M Competition in for tuning and testing. Having spent considerable time with the S58 engine previously, we already know what an absolute masterpiece this engine is. We know it generates some pretty impressive numbers from stock, so know the tuning potential here. After an installation of our 3 Channel Pro Petrol chip tuning box, it was up on the rollers to see what the engine could achieve.

It’s also worth mentioning that these vehicles currently have a locked ECU with no way to read or write the ECU data. This means that while traditional remapping is impossible, our tuning box can give owners the opportunity to make fantastic gains without requiring a traditional ECU flash. This has the added benefit of being traceless once removed for warranty purposes.

Dyno testing before and after shows healthy gains across the rev range, with a significant increase in power and torque, really transforming how it feels to drive.

Peak power was significantly increased, as we were able to lift it from 510hp at stock, up to 640hp with the box. If you take a look at the dyno graph below you can see how we change that curve (dotted red and blue lines). We give real consistency here, really opening up that mid-section, right up to that top end where we provide that additional +130hp at its peak, really transforming how it feels out on the road.

Torque also saw some impressive improvements. At stock the engine produced 674Nm and now 820Nm with the box. If you take another look at the graph (solid lines), again you can really see that consistency, where we hold those gains across the entire rev range, delivering those increases exactly where it’s needed, adding that +146Nm at its peak.
