I would be staying stock. The exup is mainly used with throttle roll off to decrease noise.

But to get it right. Dyno.

I still get those 'oh shit' moments.... The day I don't, is the day I stop riding.

The exup is full open after about 6000 rpm, it really doesnt do a lot apart from noise, with it disabled you wont notice any loss in power or torque down low. Nothing flows any differnt up in the rpm, so no map changes as such are needed, Just open tune ecu, load the map from the bike, or read map, then uncheck the exhaust valve box, download, and away ya go.

Try the duffboy map I think its called that. I currently have that on my bike and I have no cat, disabled exup valve, intake disabled, dan moto exhaust, and KN.

Bike is killer.
