The tune you will receive from Rienhart will be a modified canned tune, you supply the basic mods you have done and they basically plug in what should work.
The best real world tune is on the dyno, with someone that knows what they are doing.
IMO go with Delta Force , special forces, its affordable has allot of parameters and you can alter your tune when you need to, you can also do basic data logging. Some people have had bad luck with Delta, but I have had great customer service, support and the product works flawlessly.
It takes a little time to get right, but well worth it, my car is pretty heavily modified and it works like a dream.
