Loosing power from 3200-5000RPM
 

I seem to be loosing power between 3200RPM and 5000RPM then it seems to pull harder after 5000rpm. It starts to boost at 2800 and the boost seems to maintain 15-16lbs throughout RPM. Not sure if thats normal or not! Also seems to be no difference in boost between half and full throttle! When im pulling a steep hill and trying to maintain one speed it will bounce up to 16lbs and back down to 5 just by a slight movement of the throttle! not sure if they are all directly related or not!! Any help would be great guys! thanks
