If your vendor mentioned to you he had installed a jet kit of some kind such
as the Dynojet Stage 7 or similar you might have to learn to live with it,
since with these kits the v-boost is left open or removed and steady engine
under 3000 rpm is not possible. If you get the carbtune make sure your
v-boost is installed and in the closed possition. I'm on holidays right now,
but I'm sure TC can give you enough information on what I'm talking about
and help you out.
PS. does anybody know the exact diameter in m.m. of a standard front wheel
with the laser metzeler tyre, I have to introduce the right figure so I get
the right speed reading on my SPA rev/speedo unit.
