Question NEW ICM didn't fix misfire! PLEASE HELP!

Ok so I got in today a new ICM and it didn't fix my problem my misfire problem. When I go from first to second and roll into it, it feels like the car has hit a wall. It just studders and shakes until higher RPM when it clears out a little. The car still boost, but the car is so slow now. Could my problem be a plug, coil, or injector? I use bkr7e and gap to .028 and will be changing them tonight.. What else can I do?
Please help as much as possible.
Thanks!

Are misfires your only codes? Any of what you said can do that, and I think the "race" N75 can screw things up as well.

Yes misfire is the only codes..I can't find the bkr7e's anywhere...it just studders like it can't go anywhere. Maybe I'll change back to stock n75 and see what happens

Hows your fuel pressure? And, you ask how if coil/plug/injector could be the cause...you didn't check the coils already? That's usually the first to go.

True but sometimes it does happen in multiple cylinders. Has 132k so it might need to be changed
