Without going into details, I need a new tuner. I have a few local shops, Piedmont Custom Motorsports and Fastlane Motorsports. Would/should I be better going with an email tune or go with one of my two local shops. I don't know a whole lot about the local guys, I've heard good things about Fastlane's cars though. I already have a SCT X4. I know who the reputable tuners are here on the forum. Datalogging isn't what I call fun, I would imagine the dyno is the better of the two. My car is pretty much stock with the exception of the GT500 mufflers. I can tell a ton of difference with my current tune vs stock, that's for sure. I'm just getting detonation at WOT, it's faint, but it's there. I was all "set up" to meet with the tuner while I was down in his area, then got no responses as the time came for me to drive down there.
