Randomly found Precision by internet. Not happy with Bernhausen previous work and needed immediate care to correct problem. The technicians at Precision listened and consulted back and forth and didn't proceed until they had the okay from us. Very thorough and confident. Our truck made it to Kamloops and back with much quieter performance and no longer had the constant diesel odor. Thank you for the thorough job and we will highly recommend you to our friends with diesels as well. Thank you for your honesty and thoroughness.
