Hello guys,
Thanks to your suggestions I've done a few upgrades to my baby, love it, now what?

Got the 4.10s, diablo tune, Flow master catback and CAI. Where should I put my money next? TB/Plenum 70 or 75mm? X or H pipe? Pulleys? Headers? Don't know what to do next as far as getting my money worth out of it. Not really sure if ever going to put a blower on it. What about the Granatelli coils? worth it?
Also is there a meeting club in the Tampa area??? I used to meet my guys when I owned the Lincoln LS, nice moments. Would like to meet mustang guys (or girls) now.

Any suggestions/ideas/advice? Thanks....

 

Stay away from GMS. Aftermarket coils are only worth it when your stockers become shot and even then, its not going to increase performance (unless you have crazy boost or N2O system that keeps blowing the spark out). Doing the exhaust (headers to tips) is a good start, just make sure you use long tubes because for the hassle, shorties aren't worth it (tust me). As for TB, a 70mm and plenum is fine. 75mm pieces cause issues w/ your A:F ratio and is only needed in boosted apps. For a CAI, just stick a K&N in the stock one and remove the silencer and call it a day.

 

So just complete the exhaust and 70mm set up. Do you think I'll need to re-tune? Probably cause of the headers huh...

 

You should be fine, but if you want every last bit of power, then yes.
