ok so before i say what its doing i will tell you this. i have already replaced the trottle body, intake manifold w/ gaskest for both, deletted my emissons completely, replaed spark plugs and wires, transister pack and coil pack. none of this fixed it. ( i had that stuff laying around)

so it only missfires when im at WOT, in any gear, it starts if im runing anything over like 12 psi. ( i know i have mad creep too, i have it set a 15.5 and it creeps to 23. i understand some porting is in order) i have know way of tuning for high boost, running stock fuel system, no rewire on the fuel pump ethier. i have not run a log, for i have no way of doing so.

i was woundering if maybe it could be missing ### im running lean. i have also been told that carbon build up on a valve could cause a mis as well.

maybe because my knock sensor is bad, it seems unrelated but thought i would through that out there too.

any help would be nice, ive been having to drive my 240 and im missing my eclipse.
