Mac's Performance 14851 U.S. 377, Fort Worth, TX 76126

"Mac’s Performance really hit it out of the park with my truck. I came in with a blown up cp4 in my LML duramax. They looked at it and quickly diagnosed the issue and was upfront with the costs and repair info. If you need any work done on your diesel truck this is the place to go."

"Mac’s performance solved my problem with 2016 Colorado duramax. I needed a full diagnostic done to find out why my NOX sensor was throwing a code. I bought a new sensor and still getting the same code. So I decided to take the truck to Mac’s and get diagnostics done. I did not want to guess anymore of what was wrong because that can be really costly. Mac’s Found a cracked inner cooler hose cold side. That was the problem the whole time and not the sensor. I will only go to Mac’s for now on with this vehicle if new problems happen later down the road. Excellent service and really no wait at all. Thank you Mac’s!"

"I’ve had a 7.3 and a 6.0 in the shop. The 7.3 just had some performance upgrades, and the 6.0 was a complete cab off, Ford reman bulletproof with warranty. Each job was done great. There were a couple of little things that I had to come back for, ( expected for a job like that), but Joe always got me in and out in a couple of days. Prices always right - when he charged me. I trust this shop and Joe’s opinion."

"Been going by Mac’s for 15years without a need for a diesel mechanic but when I found myself in need of one Mac’s was the first place I thought of. Very friendly and professional and had a major issue with my Ford 6.7 analyzed and fixed in a very timely manner. This will be my go to mechanic from now on. Thanks for the great service."
