Anyone has experience with the products of www.racechip.de ?

I'm searching for something to increase the power of my 520d.
Real chiptuning would cost me in my neighbourhood between €800 and €1000, I'm looking for alternatives. So I found this:

http://www.racechip.de/racechip-chip...0d-3838-r.html

Advantage of this product is you can install it yourself, moreover installation looks really easy (watch the video on their website). My plan is to buy the cheapest version, install it, and every time I go to the BMW service I will remove the chip. I emailed the racechip support and they said to me their is no chance of finding traces of the racechip when it is removed. since the racechip doesn't overwrite any cardetails, BMW diagnostic tools wouldn't be able to find traces. In this way I keep my 2 years warranty.

What you think about my plan ?

If the look carefully the can find traces.
Why dont you buy BMWs own Performance kit? Full warranty.
