The biggest issue with re-flashing the ecu is that if its done without minor tune ups to the engine its a bit of a waist of time!
The 306 hdi responds really well to re-mapping and if done along with a free flow exhaust and air filter it will feel like a new car.
Do a search for diesel re-mapping try to get a mobile service that can do the work at your home and ask them to tell you what performance improvement you can expect, also ask them for the number of 306's they have worked on.
