I wish I had gone r-tech, as I had nothing but bother with my revo map, and revo hq were really unhelpful in resolving the problem
If you don't mind me asking, what went wrong and who did the mapping?
I spoke to Revo once regarding an issue I thought I had and they referred me back to the supplier, which in my case was fine as they're more than competent and understand what they're doing.
Their file was telling the throttle to close on gear shifts which was causing a power delay (dsg).
Same with you, they referred me back to the dealer, but after replacing mechatronics, coil packs etc, then telling me that I needed a dsg map to cure it proved that the dealer was and is not competent enough in what he was looking for when logging.
This went on for 9 months and revo hq offered a refund, albeit through the dealer, the dealer agreed at first, and then refused claiming that I have made them out to be a liar and the fact the car had been mapped 9 months previous, even though the fault was picked out right at the start
