2 o2, or not to o2

[AwDdsm91]

i have a 2g and had a 2.5 turboback done with no cat, i opted not to put the 2nd o2 sensor back in and I am not throwing codes, but i dont feel like i have as much power, my A\f says im running fine, not rich or lean, but those A\f are crap anyways, what have u guys done with your 2nd o2 sensors and what should i do

Its just your imagination. The 2nd o2 just checks cat operation. Look elsewhere for problems.

Surprising you haven't thrown a CEL though, maybe your CEL is burnt out?
