Purchased a tuner and a tune. When I got the tuner in the mail and put the new tun on my 2017 Mustang all of the lights went out on the dash. When I called back the guy that answered the phone in the tuning area said he was busy and call back. Called back several time finally got a guy that said something was wrong. Said no kidding and I get a different answers from each person I talk to. Then finally got a new tune but I have not put it on after returning the car to stock. These people have know idea what they are doing. This cost me $500.00 plus, and they could care less in as much as they already got my money. Don't let then touch your car and don't let then put a tune on it. Find someone that knows what they are doing because the morons don't, and don't care
