Yep, another map would be needed, wouldn't be massively different though, the main problem I had with the AEM was that I had to start from scratch, now I have a decent map its easy. Its on a case of changing the fuel and ignition map to suit, save on it on a lap top and then I can upload different maps for different turbo's, fuels, etc.
Next thing I must do is a map for high octane fuel to see what a difference some jungle juice makes. Should see confortabe over the 600 mark me thinks. Trouble is I can't put the power down as it is, in the dry spins up all the way through 2nd and a some of 3rd so why do I need more power? I just get bored to easily I think.
