Default No O2 sensor

I getting dual exhast done right now. There are not putting no holes for the o2 sensor. I have got my truck tune with no cats so i think the rear ones are turned off. Is it ok to drive with no O2 sensors?

You need the front ones, but you'll be OK without the rear ones if they've been deleted in the tune. The front O2's give the PCM the info it needs to properly adjust your a/f ratio.

u definitly need the front ones:-P if not then your pcm has no clue how much fuel to dump and adjust to

the rear ones deleted are fine, they just need to be turned off so its no ses light

Unless you are running an open loop speed density tune you'll need the fronts. If you ever go with forced induction you might also want an extra bung for a wideband O2 sensor to monitor your AFR and for tuning.

It's probably not the best idea in the world but it'll probably be ok to do so.....it'll run like dogsh!t though so be prepared for that
