Once again these guys came through for me on a truck that would not pass emissions. I sent it to a mechanic near my office but they were unable to resolve the issue. I love that I can count on these guys and know that the job will get done right. If you want great results this is your best option. I dropped off my truck on Monday and it was finished by Wednesday, considering this was fixed twice by someone else that took over a week that is phenomenal. Thank you Hi Tech!
