There is 1 modified tune from Tuneboy "990 SuperDuke,Dyno tuned with standard pipes (Off road use only, Not using O2 sensor) "
Basically they've taken an akra map & dyno tuned it for the stock exhaust. I think BigThumpa may have used it, but now he's sold his bike. You may still be able to get in touch with him to get some feedback on this tune.
Cheers,
