O2 sensor
I have an 87 Blazer with the TBI I took of the stock manafold off and put flow tech headers on. Do I need to put the O2 sensor back on the headers? if I don't what are some of the pros and cons of having it on verses not

The short answer is yes, you need the O2 sensor.
The ecu uses the O2 sensor to determine the injector pulse width. If you do not have an O2 sensor installed, the truck will still run, but it will not run optimally.
