which MAF? 73mm, 76mm, 80mm??

[90dpscoupe]

Cool, i have one ads chip, i got it for free, but i dont feel a difference, or see it on timeslips, although i was told they are made to run with o-r h-pipe, and a colder stat, not sure if this is true, but sounds about right??

I still have cats and stock temp stat.

And i'll have to agree with bada$$lx, subs are a must for any stang, i posted about my friends 85 coupe that had some welded, the car felt tighter, more responsive, i cant wait for mine.
