thank you for input

thank you guys in advance , i’m flying a m20k 252 tse with the rocket conversion , my usual power setting is 31 MP , 2300rpm , burning 18gph , mixture knob back one inch 10k ft .tit hottest cyl 1540 f. On my last flight , mixture all the way in (rich) , same power setting 17gph, same alt, tit stays on my hottest stays at 1540, did notice that when i started at idle cold & i pushed forward on throdle it hesitated a bit until it warmed up

i noticed on my last flight , i had to fully enrich the mixture to keep TIT in optimal , the higher i flew the more i noticed i had to enrich, any ideas what could be causing it
