There isnt really gonna be a cheap tuner out there but id go with a mail order SCT Xcal tuner. That way they can adjust your speedo, firm up the shifts in the auto and adjust shift points for maximum performace as well as get the max performance out of the engine. With that tuner u can also do some of your own adjustments too right at your home

Check Ebay -- I got a used Diablosport Predator for $250 shipped. But make VERY SURE (ask!) that you are getting a unit that is not "married" to a car. Only buy from someone with a proven feedback rating and make sure you use Paypal so you have some recourse, "just in case".
