You could have him e-mail you a tune ahead of time and make your decision then. For me it's worth it because I have a stall and rap to 7K RPMs. The transmission is a little hard to tune due to that and I'm extremely picky. Some things I cannot describe over the phone or e-mail simply because I don't have the knowledge... so having him sit in the car and go around the block would be nice.
For you, I think he'd probably get you squared away in a few tunes without even touching your car. Even so, if he comes out, I can let you know and you can meet him (or jump on the train if there is enough time for you to).
That said, I only have 3 people interested at the moment, we'll need a few more to make this happen.
