Chiptuning or Powerbox

Since a few weeks I'm a proud owner of the new Z4 (2013 LCI sDrive20i Automatic transmission). Now I want to tune or let tune the Z4 but I doubt between Chiptuning and using a Powerbox (ie RaceChip, Speed-Buster and so on).

I have the following questions:
- What are the pros and cons about Chiptuning and the Powerbox
- What are good brands, reasonably priced (< 1.000 euro)
- Belgium, Netherlands region

Any advice will be greatly appreciated.

I have JB4 but since I have ordered dps and getting an intercooler soon, I will be needing a more precise tune. So I think I will be getting one from Evolve.. I hear many good things from people using it..

What is the advantage of doing that vs. just starting with the cobb in the first place? Is it methanol injector control on the JB4?

sorry, I might have misunderstood. Are you suggesting to get JB4 instead of Cobb or Jb4 AND cobb
