i think you are getting prices mixed up, mobile mappers are charging 300 plus travel costs.
its r tech and red dot that are giving the 200 price for better maps.
be careful what forums you believe as some mappers are staff on some and delete any posts that go against them
No, there is no mixup. I booked mine in for a map next week, on the phone with Nigel today and he did indeed confirm that it was a special he was running and it is £200 all in and installed at my house.
I can understand your reticence with this area, as from a couple of posts I read, it seemed you had an issue of some sort, following a map. Fair enough, as I said speak as you find.
I do have a little experience of what the modified Multi should feel like and the little foibles under hard acceleration if you're not careful as I ran a 51 plate JTD multi almost from new for 3 years with a digital tuning box.
I ran a TDi Seat Altea with a Celtic remap for over 3 years as well, and had a custom map done when my sports car had a turbo kit. RR for that one.

I know forums have folks around who are affiliates and such and those who regularly read what is written about them. I am a mod on an MR2 forum myself and have spent a few years on seatcupra.net.
I will report back on here, to share my experience, no problem.
Hopefully my experience will be positive,a lot of multi chaps are satisfied, so some signs are good.
I do appreciate you trying to add a balance, no worries.
