EGR valve map out

Hi guys - I've had my EGR valve blocked off with plates some months back and now got my mot coming up...Could anyone recommend someone in West Sussex to map out my EGR to stop engine warning light displaying (currently constantly on)? If only route requires a full remap for extra bhp, may well be swayed! My car is 2005 2litre tdi 140bhp...thanks muchly for any advice!

I've been weighing up using Alltech /Angel tuning in Tunbridge Wells (reading up positive posts on here about Angel Tuning). Anyone got experience using Alltech - or suggest/recommend any other companies??
