Greetings!
After a heady amount of research, I may be picking up an X1 xdrive28i for the wife. One of the first mods (post break-in) will be a tuning option. Has anyone on the forums looked into or installed either of the following?

According to Hartge's website, their application is directly for our X1. To me, this is the better of the options - despite the price difference.
Opinions?
