Alright guys my truck is running like **** for lack of a better word. Anyway, i put the headers on and added a magnaflow muffler to the mix last week. I got my new tune from nelson and he turned off the rear o2's so that should be fine. next thing i know, my SES is on. Also feels like i have a major miss. I run the codes and these are what I came up with.

p1134
p1154
p0131

Last week, when it started to run shitty, i pulled out one of my brand new tr55s, and they were totally black in less than one week. And the whole drivers side was like that.

I also put two brand new bosch sensors at the same time.

I need help.

P1154 Heated Oxygen Sensor (HO2S) Transition Time Ratio Bank 2 Sensor 1

P0131 02 Sensor Circuit Low Voltage Bank l Sensor 1

i had 1134 but that was due to a bad o2 sensor replaced the 02 and that fixed it i dont know about the p0131 maybe a corroded connector or such

Looks like a problem with the bosch O2 sensors to me. Try the ones you took out if they are stockers.
