I have known Rick for years and he did all the mapping on my last Edition 30 including switchable maps and a DSG map. His work is awesome and he is REALLY knowledegable when it comes to mapping, he really does know his stuff!
My Edition 30 had all the "stage 2+" hardware on so was running plenty of power and it went really really well!
You will not be dissapointed if you go to Rick!
Ask him to take you to one of his girlfriends chip shops for some food too, lovely fish! :)
