Mapping near/in London

Anyone can recommend a good place to map, i had the center silencer removed, and it has the dreaded flat spot, yesterday for the first time to i had a pushed peddle downs and car kangaroo'd as if the flat spot was happening again and again, that never happened before and was back to normal immediately.

so im guessing a map in needed...anyone can recommend?
 
When stephen [MENTION=4601]Stephen[/MENTION] had his 200 and he was looking for a map along with me having the Meg done, the ONLY place that came up was MWM ( [MENTION=28766]Kelv[/MENTION] put me in contact).


However, after a number of call (not being returned) and messages (to which he replied) he could come back with any details such as prices etc so assumed he wasnt too fussed about the business.

No longer have his details but if you wish to try then in sure Kelv can help you out.

Other than that would only go for RS Tuning
