It just came across my mind that when i decide to go get my car tuned...that i have no o2 sensors? will this effect my engine performance, because i know wideband tuning,you hook it up from the o2 sensor on the headers...but since i got some bootlegged headers, that plug for the o2 sensor is closed shut! what should i do...?!?!?!

 

cut a hole weld in a bung and install a o2 sensor
for wide band cut another hole and weld on another O2 sensor bung

 

Yah. You'll most likely want to get an O2... I guess you'll want 2 since you're OBD2. Are you converting to OBD1??? The tuner should be able to disable the engine reading from the O2 sensor for partial throttle if necessary.
