unfortunatly its probably your only option, the company wont send you their map - whats to stop you sending it on to others ?
another option might be try chipped uk

they do the self tune mapping (other companies also do similer things) where they send you the tuning device and you read your standard map and email it to them with what settings you want - economy, performance or race - and they send you the files back.
they way it works is that you can only put the new maps on while the standard map is stored on the device. so you cant put the performance one on yours then go to a friends with it and try and put the same map on theirs.
again you would have to see if they have the maps avalible for your model and there is still the possibly that they need to remap on a bench - you would be without the ECU for a while
