Simple - Call American Muscle and get one of their tuners.
You'll get 3 tunes and tune for life. Check out and start searching. That's where a lot of us started regardless of what we are running now.

Cobb Access Port
MAPerformance Tune, CAI, and Intercooler
NGK 6510 Sparkplugs
Everything else is for show.
