Most E39 M5's will produce in the region of 390-395bhp on our dyno. With the ECU remap we generally see anything upto 415bhp on a stock vehicle once an adaptation time period has elapsed, even more on a modified one.
Through careful remapping of the factory BMW DME tables, various elements such as ignition timing, fuel delivery, and part throttles are reworked to create performance gains.
The result is an E39 M5 which feels far sharper and pulls harder through the rev band. During this process we also create new tables and tuning to enable deletion of the expensive and unreliable Mass Airflow Sensor. If you've experienced failure of this item you'll appreciate this feature, especially as it may happen again!
On top of this we can also offer the option of engine management light deletion for those with exhaust modifications.
Our engine tuning philosophy is to improve driveability and enjoyment. We do this by giving an increase in power and torque for the whole rev range, and not just a 'glory' BHP figure found at high rpm where you don't spend the majority of your time. Our figures are also very conservative and can easily be replicated on other dynos.
Overview:
- Additional 15bhp on a stock vehicle
- Fully developed on dyno and road
- Top speed limiter removal
- MAF deletion
- Sharper throttle response and drivability
- Flash from home convenience
- Return to stock anytime
- We cater for any range of modifications
