Hi AMG fans,

What do you guys think, which one would you choose?

Any direct experience with one of these tuners ?

I think both a reputable companies. I've been planning to do some upgrades this summer and was leaning towards Weistec but primarily because they are local to me (about 10 mins from my office) and I like the idea of being able to talk to someone in person for support purposes.
