"The rpm limiter is now 7200rpm, but i am not sure, that's car going better. "

Don't expect any great miracles from the "just Software tuning". You will notice a slight difference and it will get better after a few hundred kilometers as new data is written into the adaptive memory. The idea of the Software tuning is not to get more obvious power but to balance the available power better. You will find that the DSC control will not bite so aggressively and that power will be much smoother over the whole rev. range. If you want lots more power and real bite when you hit the accelerator then there is not really any way around a smaller pulley-wheel on the compressor.........to begin with.
If your rev. limiter is now set at about 7200rpm then you have the MTH file on board......so....stop worrying and enjoy.
