Narrative:
On takeoff from hou at 400 ft, the egt on #2 climbed to 938 degrees, causing the red overtemp light to come on. After checking with the captain, I pulled the thrust lever back on #2 enough to keep egt under 930 degrees. The N1 was now back 5 percent below #1 engine. Total overtemp time was between 5 and 10 seconds. In the upper 20's on altitude, the #2 N2 climbed to 105 percent. After pulling thrust back, captain called dispatch and maintenance control, and made decision to divert to dal. The divert was a little busy, but as far as I can remember, we were able to follow all ATC instructions in a timely manner. Landed uneventfully in dal. Got different aircraft and continued flight 2 hours late.
