Having had my Mk4 mapped by R-Tech I definitely know where I'm taking my Mk5.
Over the years I've been into cars, had most companies work on my cars. Nick at R-Tech is without doubt the best, not only are his maps superb he has customer service down to a tee. Treats each car as his own, and doesn't just wack a map on and forget.
Can't wait to get mine done.
