Garrett is extremely professional, courteous, patient, and knowledgeable!!! I couldn’t have had a better experience hands down!! He has my Challenger running hard as hell with the mods I did. I would recommend him to anyone that wants the best possible service/tune!! Turn-Key is no 1!!

Just had Garrett remote tune my 2017 dodge charger. He is the real deal. He had the stamina to be patient through periodic connectivity issues and scheduling conflicts of a busy life. He is skilled in his craft and true to his word. I had a dyno tune done locally by someone else that left my car feeling heavy and bogged down with what felt like a very narrow torque curve.. I didnt realize till after Garret finished how much more pep I could get out of it. I am very satisfied and grateful for his work and highly recommend him.

They are so knowledgeable and honest any questions I have they answer no problem. Very quick to answer and get back to you. I have been to shops where they don’t let you ask questions, don’t let you see anything. They don’t want you knowing anything. NOT THIS ONE. Turnkey guys are so kind they let you ask questions, they answer all of your questions. They have Dyno tuned my challenger, which is amazing. It’s running so well not to mention the Gains they made me! I’m definitely recommending them to many people and will be back for more work myself.
