I dont know about that one. A/F is useless in that sense but many a top speed run came to a halt because of EGTs. You likely wont get into any trouble with a stage 1 but I keep my eyes glued to it anytime I'm at WOT (probably whuy I bump the rev limiter a few times too many) and do/would let off immediately at anything over 1600. If something is off/not working properly (like FMU malfunctioning, fuel pump going bad ect) you could be on the verge of blowing up with every run and never know it until its too late.
