YS1500 Calibration

Hi All
I have had my YS1500 for a couple of month now and one thing that is bugging me is when I start the unit I choose 350F on digital controller but it only ever reaches 250F on Left door Gauge & 225F on lower Right Gauge? I have put a Tappecue on Grate and its reads same as gauges? Is my unit not calibrated properly? A few of my friends here in Australia have same problem.
I have cooked on many different pellet grills and Digital Controller Temp matches pit temp but not with this unit.
Thoughts
Cheers
Mitcho
