The software upgrade for the E89 Z4 20i was designed and tested at our dyno facility and on road to give optimal performance with maximum safety. Significant time was taken to develop the software to give improved throttle response and factory like drivability with a progressive power delivery.
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 75-85 hp on a stock vehicle
- Fully developed on dyno and road
- Top speed limiter removal
- Sharper throttle response and drivability
- Flash from home convenience
- Return to stock anytime
- Dealer program ID number remains the same as original
- Date of programming will not be changed
