Aero data discrepancy between TO 2 assumed temp N1 on FDP and thrust setting on TMSP; FDP was@4.5% higher on FDP than TMSP. [This] has been happening repeatedly. Elected to perform TO 2 and numbers matched. Concern is that V speeds are based on a very different thrust setting than what airplane calculates. Many other crews are noticing the same issue. Began late last week for me. So far; I've only flown 767s; haven't checked if 757s are having same issue.
B767 air carrier pilot reported a discrepancy between the takeoff power settings on the flight plan vs those actually displayed on the TMSP.
