125i E82/E88 (N52) ECU Tune


Unlock the potential in your 125i with one of the most reliable and powerful tunes for your 125i on the market.

We have dyno results showing a gain of 24kw at the wheels, which translates to over 30kw at the engine!

The secret behind it is Australian delivered 125is came with a detuned N52B30 engine, making 160kw, whereas the 130i was delivered with 190kw. We can unlock this potential making the 125i nearly 20% more powerful with just a simple reflash you can do yourself at home.

Purchasing this tune give you the My Genius end user programming device as well as the tune file. You will still need to perform a read of your vehicle and then email the ECU file back to us.
