Smoky Mountain Diesel Performance

So I don’t usually take the time to do reviews but in this case it’s warranted. I’ve kept my ear to the ground and eyes open with Smokey Mountain Diesel to confirm them to be a true quality knowledgeable shop .I must say these guy’s are top shelf ! Very knowledgeable about most any light duty truck and care about the quality of work they turnout. This is NOT a cash grab shop but spin wrenches with honor and integrity so in the event you need anything, you can go with the confidence your getting the right thing done @ a fair price not the parts changing pros like others.My truck is driving

Cody and his guys did an outstanding job on my truck (2012 Ford F-250 6.7) I had my truck deleted by another diesel shop in town and after that my truck was always having problems a lot of problems to say the least. I contacted Smokey mountain diesel right before Christmas and told them my issues and that I use my truck for my company so I really… needed it done asap. Not only did they fit me in last minute but they went above expectations. My truck has ran the best it’s ever run thanks to them. Word around my part of town was to “use Smokey mountain diesels they are the best

They're the best I would never take my vehicle anywhere else even if I move out of state

Positive: Professionalism, Punctuality, Quality, Value
These guys were great! I had a oil cooler going out in my 2006 6.0. The got it in quick, took care of the cooler and fixed some other things I had going on. Honest, fair pricing, and great communication!
Services: General repairs & maintenance, Check engine light diagnostic, Engine repair, Oil change

All around down to earth people who are VERY VERY honest and try to help you the best way possible. They have my business for good !

Cody and crew runs a tight ship, scheduling was on point, work was meticulous, and performed in a timely fashion. Worked with my 2500hd Duramax for 3 days before heading out on a 1500 mile out of state trip. Haven’t seen this type of fuel mileage since I lifted the truck. 18.2 miles per gallon running most of them miles between 75-85 mph. Deleted and tuned with new fuel system and cp3 upgraded. I’d highly recommend this shop, as my truck is my livelihood

I would give this place a 10 out of 10 they are very trustworthy, accurate and effective.! The owner and his wife know exactly what I needed in my truck and had it fixed within minutes., I will also add that employee of the month is very welcoming Mr. Javo.!

Positive: Quality
10 stars! Super great service. Showed up in 'reduced power mode' first thing on a Monday. They took me right in as I was traveling. Fixed it within the hour. Great price, super service. Thanks!

Cody and the staff were very knowledgeable about potential issues, diagnostics, upgrades, maintenance and anything else I had questions about relating to my Silverado. He told me the pros and cons of each… option and we moved forward with a plan. I got the truck back in a reasonable time frame and the work was tested, top notch installation quality and part wise! I would recommend anyone with a diesel to swing by and see what they can do for you. They have multiple high end diesel part manufacturing companies that they work with on a daily basis and can help you reach your goals with your

After reading about the horror stories involving the Duramax fuel pump issues. I decided to take preventive measures and have the CP4 fuel pump up graded. I talked to Cody at Smokey Mountain Diesel Performance, he gave me many recommendations and options for my situation. We agreed on the upgrades I would like to have, I was then sent a very professional invoice showing all the parts and work to be done. They got me in the shop in the time frame we agreed upon and got the work done in a timely fashion. Now I have the peace of mind, that my 2013 Chevy Silverado will not have the catastrophic fuel

For starters they knew exactly how long I would be in line to get my truck looked at. The said 1st of August and I love the fact that they held true to that timeline. They stay very busy at this shop, and its for good reason, They know what they are doing!
I have had my duramax in 4 different shops and no one could tell me why my truck would shut off randomly and restart by its self just driving down the road, until I brought it here!
It only did it a few times at first but the more I drove it the frequent it happened. It started getting dangerous because some times it would die completely and

Positive: Professionalism
Took my 2015 GMC 2500hd duramax to them for some upgrades and add ons. Cody and his wife was really nice and down to earth people. He was super knowledgeable and helped me pick out with the best options for my truck. I'll definitely be back when I need something else done. Highly recommend!
