Default EGT jumps 200 deg Celcius..?

if i'm cruising in say 5th gear at 3k rpm and i floor it for about 5 seconds and let off, my EGT's shoot up from 700 to 900+, then slowly come back down.
i'm running evo 550's, supraTT fuel pump, small16g. etc
afc is running at -17 a/f correction at low throttle at this point and -8 at full throttle

anyone got any ideas?

I'm guessing the second you close the throttle it runs rich for a sec.
