Josh and his team did an excellent job both times on our truck. Prompt, honest and fair both on pricing and expectations. Will go to again for any future work. Thanks!

Josh went above and beyond with the repair of my AFM delete on my 2018 GMC Sierra. He was responsive and professional. He always communicated with updates.

Josh did a phenomenal job repairing my Sierra motor after the DFM system completely ruined the camshaft and lifters. Very reasonably priced and works perfectly. If you’re looking for an honest mechanic, take it to LSX.
