Seems to be a very weak tune compared to everyone else out there. You do get the benefit of the Dinan warranty coverage which is worth the money for some.
The 135 guys have been running GIAC, ESS and Cobb for a number of years now and I've never heard of anyone having issues with a typical 'stage 1' level tune. And yes, they are all about 50% less expensive.
Also with some tuners you get the benefit of being able to load/unload using a module that plugs into the OBDII port under the dash. This is very convenient because if there is a software update or BMW reflashes your ECU you can simply reload it sitting in your garage in about 15 minutes. With Dinan you will have to bring the car back to the center that did the 'install'.
