I have been in talks witih R9k since yesterday. They have already quoted me $295 for a tune, 2-3 days priority mail turn-a-round and I have the form not to sign and get this done. They told me they haven't done any tunes for anyone in the States. I sent them a pic of my ECU and its number and they think they can reflash it. But they will need it at their facility to be absolutely certain.
However, I am looking for some links in forums about what people thing of there service. I have heard that it is good but want to actually read through a thread anywhere. Been looking but haven't found anything yet. Just hearsay!
