So im thinkin about getting either Eurobahn software or the Powerchip software for my 05 X5 4.8is

The thing I like about Eurobahn is that I have an actual shop I can go into in my city to get the software installed.The Powerchip has to have the ECU sent in.

Also the Powerchip asks what gas you use, and Eurobahn does not. So im wonderin if maybe Eurobahn is more flexible and more adjustable to not even gas but maybe basic mods as well(exhaust, throttle body, intake)

What have you guys heard about Eurobahn and Powerchip and diff between the two??
