Help ASAP w/Problem

[twack]

I want to go to the dyno day but... I upgraded to a 50trim and MAFT. Got it all setup and now it runs like crap. My wideband shows that at idle it leans out till --, and the logger fuel trims wont change from %100. So i got a new eprom ecu and o2 sensor. Still runs like crap, now the wideband may be bad but you can fell the car runs terrible and dies on deaccel and half the time at idle. I really want to go to the dyno day so any help would be awsome.
