Narrative:
At 8;500 ft on climbout; we noticed itt [interstage turbine temperature] on the number one engine exceeded limitations. Thrust was reduced to 85% to comply with limitations. As we leveled the airplane and brought the number 2 engine to 85%; we noticed the N2 on engine number 1 was 5% less then engine number 2 and the itt on number one was still 200 degrees higher. We decided ZZZ was the nearest suitable airport to divert to and I declared an emergency. We contacted dispatch and maintenance and proceeded ZZZ. I informed the passengers of our situation as well as our flight attendant. We determined we would be overweight for landing and I decided to land overweight instead of burning the extra 1;700 pounds of fuel off. We landed without further incident.
