What tuner are you using with those mods you have listed in your signature? Who tuned the bike?

Sounds like it's all in the tune to me. Are you sure he tuned it or did he just put a canned MAP in it? Have him get you a copy of the MAP that's in it and e-mail it to me if you want, I can tell you what adjustments he made or didn't make. It sounds like your bike is either getting to much fuel or not enough in those ranges to me, which would be in the tune. If you want you can PM me and I can give you my e-mail addy for the MAP.

Could be the tuner itself is faulty.

Tuner as in the tuning device (SERT) or the person doing the tuning (operator)? My bet is on the latter.

Then that's the problem. The canned MAPS aren't spot on for your setup. The tech should know this. You either need to dyno tune or learn to smartune. Or find a MAP more suitable to your build. (but I would still do a proper tune).
