HaS anyone any experience of these mapping their cars?

I would go RST but for this price just to get rid of a flat spot (as we all know a N/A gains almost zero power from a map) I can't complain.
I want my clio 197 doing to eradicate the common flat spot problem which is £175 but they said they can map my megane and the clio as well for £300.

Anyone got any info on them?

 

Im Manchester so not too far. I'll have to contact them!

 

Is that with clio's looking at your avatar or does he have a decent knowledge of megs too?
