No chance 1500 - 1600 is normal, it can't be adjusted without huge hop up options because it falls within the first 20 percent of the FI map and most tuners can't go in at that stage, besides when the guys tune for Hp it's seldom at idle or small throttle opening, you also do not want the thing cutting out on a hot day if idling to low and going from N to first gear, a problem seen on many of the newer KTM's ...and for witch they say they will develop a cure for AIDS before they can fix this annoying problem.
So let it rev, and open the fuuuurken gas brother, or trade it and get big boy 250 with a carb and idle up screw
