Dont buy a map on price,
A good reputation and a good knowledge of the car they are mapping should be top of the list.
 
You could probably get one for £50 but as above you want experience reliability the best performece you can get from it and most of all someone who knows what there doing if it goes wrong it can go very wrong ;) I'm sure someone can recommend a good tuner near bromely/sevenoaks ;)
 
The current revo £100 off is real good i've done it with no complaints and there are loads of places around the uk that can sell revo. Also as said above don’t go on price as the inexperienced tuner could just max out everything on your car which may be great for two weeks until boom!
 
This is the problem Iv had.
You hear different things about different tuners.

This is why Iv not had mine done yet.
Dont know who to use.

Good luck with your mapping.
 
I'd stick to someone as local as poss and someone who has a good rep.
You dont want to be driving 150 miles with a problem cos you chose a mapper who is miles away, the same goes for if you want the map tweaked.

If your in or around London I'd highly recomend AmD Essex
 
awesome gti/revo will only map a 110 to 135! anyone ever heard of carbon chip tuning south manchester?
 
The last time I had my Ibiza mapped I went with Custom Code and had no problems. At the time Revo were also one I was thinkin of but read that there maps were pretty aggressive where as the CC was more progressive through the rev range.
