From their site:
Singh Autosport is North America's No.1 vehicle performance software developer. We have over 19 years of experience in reading, writing and developing vehicle performance software for European cars. Whether you drive a Mini Cooper, a Ferrari Enzo, a Mercedes CLS or a Rolls Royce Phantom, Singh Autosport can make your car drive exactly how the engineer's intended - with maximum potential. Nearly every vehicle on the road today has been de-tuned to protect it from careless drivers, neglected maintenance and low quality fuel. To make your vehicle drive to its full potential is quite a simple process - we download a copy of the software from your vehicle and then upload a modified file that will definitely improve the car's performance. The benefits of the new file are as follows:
- Improvement of fuel economy by 10-15% Maybe, but my driving isn't for fuel economy .
- removal of the speed limiter (if desired) Never tested, I'm too chicken to get another ticket .
- raised rpm, increase in power, better acceleration. Night and day proven difference
- and smoothness with no flat spots or hesitation. Hell yeah! I love it

Money well spent!
Others, please chime in.

 

anyone got their 2004 525i tune by Singh?

 

Does anyone have an actual dyno that shows before and after tune data? Everyone seems to agree that the tune is good, but no one has any dyno results to prove it.
