Thanks for all your help, but I do need to know how much of a hassle it would be switching back to obdII to get my emissions done every year. Yes I live in Forsyth with unfortunately needs emissions testings. Would it be worth the extra $300 to go with the AEM system for my car ($1099) so I wont have to change out stuff except my tune to pass emissions? Or do you still recommend me getting a p72 w/ hondata s300? (about $800 for new stuff).

And what is the difference (performance wise) between tuning with hondata and tuning with AEM?

Thanks, you guys have been a great help!
