New guy... just bought my first 2007 Mustang

I have been a BMW owner for a while now but after my last upsetting run in with the local dealer i decided it was time for a change so i did some searching and decided a mustang would be a nice change. My last bmw was a 6spd manual and after driving it daily for almost 2 years i got a 5at in the mustang, every now and then i miss the manual but for the most part its nice to just cruise and not worry about it.

So far I have tinted the windows 20% all around, put on a K&N CAI, swapped to 3.73 Ford Racing gears, and i bought a diablo predator tuner.

Some future mods im looking into are exhaust, tires, some various body items, pulleys.... and my goal for next summer is a whipple supercharger.

Like i said this is my first mustang so any advise on anything is much welcomed!
