Would you be buying it from the actual company store (assuming it will be called TDI Tuning) or would it be an authorized reseller?
Cause as it seems the actual company (from reading the flyers) would just sell you the box with the preset settings(map) for the Bravo, that they've set as the general best setting(map) from testing on maybe two different Bravo's.
If it's an authorized seller, which it sounds like and from following what that guy said, I'm assuming that he will indeed do a remap of the tuning box with a dyno run for your Bravo, which is great news indeed. This means you should get 100% performance out of the tuning box
Or he could mean that he'll get the standard tuning box, then have to download a Bravo (whatever engine you have, sorry that I don't know whether you have a multijet or tjet

) map then put it on the tuning box and then plug it into your car...
