@studio460 just playing catchup here - in my signature you can find my Tuner and Tuner... LOL I went the path of HPTuners.com
That said you need the following - laptop/Windows - $499 for the Tuner itself - $100 in tuning licensing. Then you pay the tuner themselves.
STAY far away from cheap tuning gimmicks - though talk to me about drive by wire throttle controllers - they work with and without tuners. I have a horror story I posted here about my experiences with a company now owned by Holly. That said good luck - sometimes the real popular tuners (people) are hard to get responses from. The truth is - at least for me - get a tuner willing to look at YOUR cars stock configuration - even if you have performed some bolt-ons like CAI and they should tune for your vehicle. Just my two cents, not everyone can digest the bolt on packages all at once ($$) - understand clearly what they will charge if you need to send logs and tweaks. Set the expectations and tell them what you plan to accomplish as projects so they know.
My 2 cents for what its worth - of course I 100% agree with
