The map for the S and GT should be different because the intakes are different. Go get the bike Dyno tuned and save the file to a Flash Drive in the event you ever have to reload it. I don't know what the prices in Europe are like but a Dyno Tune is around $100 here in the US. And remember, any changes made to the intakes or the exhaust will effect the engine tune meaning the bike should go back on the Dynamometer. So make up your mind what you want to do with either of these areas going forward before you spend the money on a Dyno Job. Just changing the brand of Air Filter will effect the tune especially if going to a reusable filter like a K&N.
Before Dyno Tuning I'd also put in new Sparkplugs, Air Filters, get the Injectors professionally cleaned, and if your Ignition Sticks are getting old, I'd consider looking at those as well.
