Pacesetter O2 Question
Your best option is to just pick up some o2 sims from someone on this site, about 50 or 60 bucks plus shipping, or get your PCM tuned and have the rear sensors removed. I suggest the tuning so you can pick up a few extra ponies with the extra tweeks at the same time. I've never had it tuned before but I've heard the lowest start at 150 bucks unless you can find someone near you that can do it for free.
