I've been running my set up in sig for about 5 years now without a tune. I have had to change the front 02's about twice which doesn't sound that horrible for 5 years. Rears have O2 sims. I know I am not getting max power but I am waiting for a tune after my H/C┌∩┐(◕_◕)┌∩┐
Man: The Mods you are fighting,
they are the biggest Men I have ever seen. I
wouldn't want to fight them!
Me: That is why no one will remember your name!

alright sounds good... now what would happen if i ran the car without the rear o2 or just left them conected ?

If you pull them out, you have a massive exhaust leak . If you leave them in, your going to get a check engine light telling you that the cats are not working........because you won't have cats. 02 sims are around $90 bucks. Just have Frost do up a tune for you. He is cheap and from what I have heard a excellent tuner. I would have had mine done along time ago but I fucked up and now with H/C going in, am obviously waiting.

i also heard good things about frost i looked into him i asked him a few questions i liked what he had to say my only problem is my camaro is my only car and i work alot so i cant have the car down for shipping time....so what im thinking about doing is going to a shop right down the road and getting a dyno tune..
aside from the check engine light what else do u think would happen if i left them in... do u think my car would run lean?

I paid about 30 bucks for 2nd day and put a bit extra when i shipped to Frost and i got it back a couple of days later. He is an excellent tuner for our cars and knows what to do to get the most power out of your car with your mods.

You shouldnt worry about your rear 02's in the future when you do get a tune it will be deleted out. Not meaning you take them off meaning you put them back on your Headers or Ypipe but they wont read anything and your SES light wont come on. Wether you tune them out or not due to the amount of unburned fuel and so on it will die out much quicker but again it doesnt matter since your gonna get a tune down the road to cancel them out. Your car will run fine without getting a tune to delete out your 02's since there are plenty of people that have done this, your car will run better with a tune though and you will be able to take better advantage of your aftemarket mods. Basically you shouldnt worry too much wether or not you get a tune but it is suggested and you wont regret it.
