P0155 code... 
What does it mean when you throw this code?
Is it just that its reading theres something wrong with the o2 sensor?
Is it a code I can just delete with ls1 edit?
I don't believe you will be able to use LS1edit with a custom 3 bar operating system on the PCM.
The code means the computer thinks the heater isn't working very well on your O2 sensor. Could be an exhaust leak, bad O2 sensor, or it just isn't getting hot enough for the computer's liking.

That's the passenger side front O2 sensor. Mine threw this code. I went to Autozone and they cleared it for me. Since I mostly putter around in the car I figured it was time to clean it out. I could not believe all the carbon **** that came out of the exhaust.
The code has not come back since.
