difference between european and us maps

has anyone done a side by side comparison of the differences between us and european buell maps?

I have tried flashing in the race maps into my ecm and it runs ok until you 4000 where is seems tail off. it then picks up again at 5000.

I also checked the afv value of my stock map before taking it out and after putting the race one in. Stock afv was 105. this race map seems to be at 112

no one compared the maps???

seems strange no one has done it

The Euro maps have slightly more timing than the US maps due to improved fuel octane. That's about the only takeaway I have, but I believe the stock header pipe diameter is smaller on the Euro models as well.

I thought the maps just had a funny accent and put mayonnaise on their fries?
