put my pacesetters on and ORY and there was only 2 places for the o2 sensors so I left 2 of them not plugged in. Is this going to affect my power? Will it be best for me to get them turned off?

you can run o2 sims for a little while but will benefit you much more if you just get them tuned out.

if you dont have a tune already it would be a good idea to get one, and have it tuned for the headers anyways so you get the most out of them. if blackbear performance was around when i got my tune i would have deffinitly got one from there than nelson performance which is more than double the money and its not even a data logging tune which is better...
