Cmgs 004 Fault Code... Help Please

Installed my cmgs x fsb kit about 2 weeks ago, install went perfect... the car was pulling like a beast... yesterday night I was trying to do a log... and cmgs started throwing the 004 code.. I checked all the wiring its rock solid, I have a very small leak neat the pump... so I taped it up... but its still throwing the code only at WOT??? any advice or help is much appreciated.
