o2 sims are very easy. all you do is plug it in and go. all the ones ive ever used were very good and never had any probs. as far as the tune no it is not a must but as with any mod to the engine a tune may get you a few extra HP with the exhaust mod but i dont think i would go running for a tune just for that. wait for more stuff. no need to tune for the o2 sims either.
