Time frame to update tunes?

[bconnaway]

I was thinking that I want to completely redo my exhaust system sometime this summer. But before I do that, wanted to know what kind of time it would take to get new tunes for it and what I would need to do to prepare for it. Right now I have a custom 89 performance tune. Exhaust wise, I currently just have a glasspack replacing the stock muffler. What I was looking at doing is: OBX longtube headers, catless w/ OBX resonators, magnaflow x-pipe, 2 dynamax bullets, and dumped over my rear axle. I haven't really updated my gryphon or plugged it into my computer in what seems like forever since i have it pretty well built into my ashtray (makes this pretty difficult) so im not really sure if there are updates I've missed or what. Just trying to get a feel for things before I really start looking into doing this. Also, if i remember right, tunes were $30 when I originally ordered my Gryphon and said they were $60 for later ones. So would this re-tune be $60 or what?
