There are 5 sensors and (if I remember correctly) are:

1. Boost Pressure 1
2. Boost Pressure 2
3. MAF
4. Camshaft Sensor
5. Turbo Sensor

Have you looked this : http://www.tmcmotorsport.com/CarProducts.aspx
It seems to be the same installation method and it is cheapest.

I am not sure if it is the same, as it seems to have only 2 connectors for the sensors. Also, if I ever consider doing a tuning, I would go only with a reputable and well-known BMW tuner, like AC Schnitzer, Hartge, Kelleners, Hamman. I would not trust anyone else.
