My main reason for going GIAC, is because they are local and I personally feel that there gains will be more realistic for me considering they are tuning and running their car in the same conditions from fuel, air, sea level, etc in the exact same paramaters that I will be in. I feel the evolve will produce less for the local cali guys then in europe for the reasons mentioned.

More convenience then anything.

Also my other concern is always if BMW is to update the ECU on the car while in service, that would override the "GIAC" tune in this case and therefore would have to revisit the GIAC dealer correct?
Yes, if BMW updates the DME it will erase any aftermarket programming. In this instance, we offer a free re-flash at your nearest GIAC dealer.
