Hi Pavlo,
To what bit were you reffering to?
Tom

 

I'm by no means an expert, but this is just my personal opinion and details of my experiences...

Tom will no doubt make up his own mind who he uses, but hopefully with all of us on here, he'll have plenty of ideas and knowledge from other ppl's experiences.

Good luck with which ever mapper you choose

 

The post I quoted, written by someone that must know more about mapping than Iain himself at power engineering to be able to make such a definitely statement about how much power his car should make. If the rolling road gave a different number but the car was no faster, he would presumably been happier.
