might be the tune with 2.8? i know some people are reporting problems with a 2.8 with the GM stage 1/2 injectors but thats at WOT. Also when u say colder plugs how much colder have you gone? and what have u gapped them at? if you are coming into boost and they are gapped to large then u could "blow out the flame" or if your plugs are too cold they could be mayb fouling? if they are fouling then clearing it out a few times should clean'm up.
