Default Has a Miss at low rpm and cuts out and pops at wot.

Need some help. I have an 08 electra glide ultra classic that is missing and cuts out and pops at wot and under any load. The engine has been upgraded to a 103 with 255 cam, kn air filter, and rush exhaust. Was turned with tts. The computer says the O2 sensors are bad but they are brand new. Only about 5000 miles. I hope I'm explaining this alright. Any suggestions or if more information is needed I'm better at answering questions.

check to make sure your o2 sensors aren't cross crossed. F ont cylinder plugged into rear and vice versa. Had this happen to me.
