Default Ignition cut under load/boost?

just the other day, the car started cutting out when under load and boost around 4000 rpms ... a/f ratio goes rich (per utec) so I am guessing an ignition problem or a/f sensor problem. Anyone else eperienced anything like this ... I am gonna pull the plugs out tomorrow.
Mods: STi pinks, vf34, utec, full catless exhaust/headers, shorty intake, fuel pump
(it does this on all maps)

many most all


What is your voltage at WOT? Check grounds on motor/tranny. Fuel or ignition issues I'd guess.

i had a similar problem. i thought it was b/c i wasnt getting enough fuel, (went from 6psi to 8.5 psi) so im just gonna upgrade my injectors. hopefully that will work. if u figure something out let me know, to the best of my knowledge there are no ignition upgrades for my gc.
