cmoss - this sounds like exactly the same problems I had after my first 6000 mile service. When I got it back is was crap, wouldn't run at low revs, popped and crackled on overrun and basically was only good flat out. The bike was re-shimmed and basic other stuff.

I took it to Sigma Performance and had FIM Ultimap chip and some fettling. Bike was transformed.

As far as I remember, there's only 2 injectors - you can get FIM chips to run with 1 or 2 injectors. I could be wrong though. Mines still running on the 2 injector setup with FIM ultimap UM239 chip (but this is for the 996S so don't get that one).

Cheers, zig
