Tune or o2 Sensors?

Since putting LT's on my 2001 Camaro, the thing runs like crap. its throwing misfire codes, idles rough, SES light flashes and gets awful gas mileage. Its got the stock tune, no rear o2's and new plugs. Where is the best place to start New tune or new o2 sensors?

Random MF or cylinder specific? What plugs? No reason LT's should be making your car have all those problems.

Not cylinder specific, just a randon missfire. Cruisin down the road its fine, but idle and traffic, she's a chugging machine.

I ran both my cars for a few years untuned and never had any problems. I would check the codes again and see if anything shows up now. I also rode my car around with both upstream 02 codes and never noticed a difference either.
