I did. Didn't go through Visconti, and I'm tuned by Payn, but yes. I was one of the first. Lemme know if you have any specific questions that Justin didn't cover in his review.
Are you asking if Botti is a good tuner? I'm sure you purchase this through East Coast Supra (which is a great shop, btw), but Botti is an excellent tuner. He holds several of the current records.
Do you have something sitting on the passenger seat? Turn off the car, open the door, the electronics should shut off. If you have a passenger, they need to open their door too.
Otherwise, it'll be 7 minutes.
