Rare, they did the map on a borrowed car from a dealership they are friendly with but couldn't get the car on a dyno to see the results from the map, the have developed the map but I just want to make sure they have the finished map and don't tweak it further after I get it flashed to my own box.
As for that, not really as they are Euro 5 engines, our cars are Euro 6 so it won't be perfect on our cars, by all means will up the power but not as well as the new euro 6 map for our cars TMC is working on
