Will I need tuning w/ new headers? I have a 98 trans am and I'm going to be installing some MAC midlengths, with an off road Y. I plan on getting the o2 sims, but will I need additional tuning with them?

some cars do, some cars don't. better to be prepared then to get caught with your pants down. my car was fine. even took it to get it dyno tuned and the guy told me it wasn't worth the 550 bucks. Id say save up some extra dough just in case...and say you dont need it...mo' mod money for later 
hope that helped. you'd probably be ok, perhaps a little on the rich side but nothing too bad.

Sometimes people need tuning, sometimes they don't... it'll just depend on your particular car. My car required no tuning at all, I just tweaked the a/f with my Predator a little to get it to optimum. 
Just be prepared that sometimes you'll be lucky and the car will run just fine with headers, but some people have major issues when they don't tune after a header install... just be prepared and it won't surprise you either way.
