So before ya get ahead of your self. Classy Pontiac is highly recommended for custom making headlights.
Now. Things I would do
Transmission cooler
transmission filter change/shift kit install
tune
catch can especially if keeping DoD/AFM
and do not waste ur money on the CAI kits u can make ur own CAI or HAI. I currently have a HAI but just made my fender well intake for under 50.
.
You could always do an intake manifold swap to an ls1/2/6 or fast intake to make a few more horses. But a time would be required.
