I'm not sure if you'd find it much better if I said "most reputable tuners wouldn't tune for a turbo sight-unseen?" I'd think you'd be off your rocker to do so without some significant data-logs before, during, & after. Not saying you don't do it well, just that if someone wants to go with a Bama or similar, they won't. There's a difference between "mail order" and "remote tuning." I have no idea which you do or don't do, but mail-order is creating a tune, writing to a chip, and mailing it. "Remote tuning" is something entirely different. From a Bama rep on another board: "Unfortunately, we won't tune for a heavily modified Mustang like yours, even as sick as it is! When you have extreme mods like this, you definitely want to go with a dyno tune. That is the only way to truly have a safe tune since there's so many different variables that can come into play. The tune could really go in a few directions, especially for drive-ability. It's much easier with the Stang right in front of your to fix these issues." That's their philosophy, and I happen to agree with it.
