Just had my bike Dynojetted & Power Commanded at Pro Twins.
Picking it up on Saturday Morning.

One thing that was highlighted to me was that the new Testastretta engine management system has an oxygen sensor connected to the exhaust manifold and at the lower end of the rev range (sub 4,000?) they can't alter the fueling because the sensor would notice it and counter the changes. It can't be disconnected either.
Bit of a shame it can't be done but it should still make a difference once the engine gets going.

I'll have the printouts and data come Saturday so I'll let you know how it feels then.

It can be disconnected , look on DML forum in USA .The yanks have actually got a class action court case against Ducati over the O2 sensor and the problems it causes.
