Our software fully maximizes the 'high-output' N52B30K0 engine in the 525i. Our software has been carefully developed on the dyno and the road to provide optimal power and torque gains at all RPM. We change the fuel, Valvetronic, and VANOS maps as well as revise the factory torque limiters. We have paid particular attention to increasing low and mid-range torque. The stock BMW software is hampered by settings for 87 octane fuel. By re-mapping the engine programming for 91 octane, we can make more power, torque, and improve fuel mileage - all without harm to the engine or affecting driveability. The throttle response is also improved (quicker) eliminating unwanted and dangerous flat spots in the pedal response.

The E60 525i benefits from two Stages of tuning -
Stage 1 - stock intake manifold, just a software upgrade
Stage 2 - 330 intake manifold with matching software upgrade. The 330 manifold is a direct bolt-on to the 525i engine and provides an additional 30hp on top of the software tuning. More torque is available as well thanks to it's 3-stage DISA system. Since the rest of the engine is the same, this gives you 330-levels of power and torque!

There are two ways to install our software: mailing the ECU to us for a reflash or do-it-yourself install with our Turner Flash tool:

Mail-In Reflash - lower upfront cost but additional shipping charges. Minimum downtime of at least three days. We have a 24 hour turnaround on shipping the ECU back to you but factor in transit time. Expert installation of your software at our facility.
Turner Flash DIY tool - higher upfront cost but files are emailed back and forth. No downtime - you can still drive the car while we process your tune. Files are emailed back and forth - your stock file comes to us, a tuned file is returned to you. Easy install via Windows laptop using these instructions (click here).

Should you choose to mail your ECU to us, follow these specific instructions on shipping the computer (click here). We will provide you a free Next Day Air shipping label to get your ECU to us quickly - and returned just as fast. We will contact you to arrange a time to ship in your ECU to further minimize downtime.
