Unless I'm mistaken, TOGA is not normally available above 14,000 ft. I think that one of the changes needed to operate the A319 at Bangda - the only airport that is over 14k methinks - is to mod the FADEC(s) to get TO thrust at this altitude. Who needs TOGA when you're not doing a TO or a GA? So, when you're looking at this in the sim, you just may get different things either side of the 14k line.
