They recently worked on my 57 Chevy, they did a safety check inspection, and lots of other miscellaneous mechanical items, temp gauge, coolant system check, checked the carb/tune, they did a professional tune on the car over 2 years ago and it is still running like a top! The owner is a great guy and his foreman John took the time to explain everything to me, these guys are true professionals, they know how to treat a customer which is #1 in my book, and I know I can leave my car with them and they are honest and trustworthy, I would highly recommend them, these guys are top notch,they do quality work, believe me I’ve been to other shops and there is no comparison, You are in great hands at DBR! Thank you David, John and the team!

Mixed feelings here. I installed headers myself and took my C6 corvette in for a tune. Picked it up same day and not 8 minutes after leaving I burnt through my clutch line. They called and had a great guy come tow my car back but then quoted me $2,700 to drop the entire rear and replaced a clutch line/master slave cylinder (a $200 piece they ordered). Which I understand that had to be done and burning through the line was my fault. But the price was significantly high. They stay busy so I was told might be a couple months but they got it done in a month. I go down there, pay, start the car and hear a rattle.... I should have said something then but was too excited to have my car back! Tune was on point, asked for a very mild burble which was delivered and I love it. But a little over a month later, still a subtle on and off rattle. Now just the other night I started my car and my Muffler popped off with a loud bang. I thought the rattle had finally showed itself, but no.... they didnt tighten something down correctly so I have a rattle somewhere in the car and had to jack the car up to get my right muffler back on.... will I use them again? Maybe

I had new heads, cam, intake, TB, tune, etc, on my LS7 swapped 2010 Camaro back in October 2020 resulting in 620rwhp with my NA motor. They were very fast in turn around time and communicated well. I was surprised and impressed that the owner took phone calls and emails as much as he does while running a busy shop. We had a small hiccup with my ECM so he drove my car back and forth to his house at night to put random driving conditions on it just to iron out the bugs and see what could be wrong. Come to find out the supplier had shipped us an automatic ECM vs a manual. They swapped it out and reinstalled the tune so it runs like a dream now! The road test tune and multi-condition tune using the Mustang Dyno is well worth the money. I appreciate that sort of attention to customer service. I actually waited several months before leaving a review so I had time to evaluate the car, and the work. Thanks again, and I look forward to more projects.

Had my windows tinted on my 2016 Ford Focus SE/RS and they did an excellent job. Clean shop, quick turnaround tine and friendly staff.

Recently took my 2001 C5Z06 on a 1,000 mile round trip from middle Tennessee to Virginia and back. It is so nice to have 500+ whp and air conditioning! I so appreciate all the work that David and Jon and his team have done on my car. Lets see...motor, transmission, rear end, torque tube, etc, etc, etc. They are professional and punctual. Shop is clean as a whistle. I will never take my car anywhere else. Proud to say my car is a DBR car.

I got tint on my vehicle and it looks great! Also, they didnt have enough of the regular formula, so they upgraded me to the ceramic heat-blocking tint for free. Great product and service!

Thanks again guys, great stopping point.

Top notch people to work with. Answers all questions in a timely manner. Fare prices for the work that is done.

Great staff and great service! Highly recommended.

David and team did a great job. On time and budget. Very knowledgeable Shop was clean and car performed better than expected

DBR Performance is the BEST! Recently took my 2019 C7 Corvette to David and his team. They did a few bolt on mods and a performance tune. The car is amazing and exceeded my expectations. David and Jon turned my fast car into a wicked fast, fun car to drive. Would highly recommend DBR to anyone looking to improve their cars performance. THANKS TEAM DBR!

Been to multiple performance shops in the past and was not happy with the work done. David and his team took my mustang to a completely new level. My car runs better than it ever has! I will definitely be back for future upgrades as well as modifications for my other vehicles. Best performance shop in middle Tennessee, hands down.

Just had a Street Tune done on my Camaro yesterday and I am very impressed with the results.

Great people, great customer service. Best work period. Honest people. YouTube Boosted931

I drove and hour and a half away to DBR to have my mustang tuned and I could not be happier with the results. My car runs better then it ever has and it was done in just a few days. Thank you guys for taking care of my baby! We will definitely make the trip for any future needs.

They don’t work on all American cars, they wouldn’t even think about working on my Ford Focus.

They are always very helpful.

Cant say enough for the team at DBR. They worked with my schedule and the results are amazing. They installed a upper pulley, E85 kit and installation completely looks factory. The time spent on the dyno sure shows, its an entirely new driving experience. Thank you very much and Ill 100% be back for future modifications.

They quoted me an extremely high price to change a cam in a ls car

Had DBR install and tune a supercharger kit on my Mercedes. They did an incredible job and during tuning they got the most HP out of the system of any similar install Im aware of anywhere! They really know their stuff!

Just acquired a 2010 Dodge Challenger SRT8, equipped with an Arrington Performance 426 Hemi stroker, Kenne Bell Supercharger, Mr. Norms Super Cuda kit, just to name a few items. Decided to give DBR a shot for basic maintenance, street tuning, general look over and to see what I can learn from them about my car, etc. Jon took his time and discussed with me some features on my car and made some recommendations. David worked on the Dyno and street tuning and got the beast running properly. She put down 757 rear wheel horsepower ! Coming from a business owner, David, Jon and the team display and provide professionalism, honesty, integrity, and superior service. Great job guys. If you want a shop you can depend on and will treat your ride like its their own, DBR is the place to have your service done.

Excellent service and very knowledgeable staff. Ive taken multiple vehicles here with great results!

Great to work with, stellar communication.

First of all, just a note about David and his staff. These guys are good. All you have to do is take a look at the cars in his shop and you will quickly see that real car guys want DBR doing their high performance work. Not only are they experts at high performance, they are also highly ethical and honest. David and his guys have turned my 2014 Grand Cherokee SRT Into a beast of an SUV. Modifications to the engine to beef it up, allowing him to turn up the supercharger boost to almost 10 lbs, a custom DBR tune, Magnaflow exhaust have produced 590 HP at the wheels according to his dyno sheet and who knows how much HP at the crank...probably close to 800. So the Jeep is crazy strong and you can definitely hear me coming. But the best part to me is that during the build, David encountered one problem after another when making my Jeep do things it wasnt originally designed to do. He put many more hours into it than originally anticipated, and not built into his estimate, yet, he stuck to his original estimate and ate the extra hours of labor. Bottom line, he said I told you it would be X, and it will be X. Only one word of caution. They are so busy with the coolest cars you will ever see that they are in very high demand. But I promise you, if you can be patient, you will be very happy with what you get from DBR.

David and staff always treat every job like it is their own vehicle, very clean facility and total professionals.

Dave and the crew at DBR are fantastic. You could not ask for a better group of folks to build your hot rod or street car.

A group of awesome guys here!!

DBR has been my exclusive speed shop for 9 years. Honest, forthright, and knowledgeable. I have strayed once or twice for a deal but I always ended up back at DBR to get it done right. My srt Cherokee puts 1265hp to the wheels and my cts v puts down over 700 rwhp with stock blower. This is world class expertise right here in Tennessee.

These guys are great. Fantastic place to take you ride.

Very professional group of people that take pride in their business. Very helpful and informative whenever I had questions.

Best tune for my car! Made my car run like a dream.

A performance shop that only works on American cars... thats a crummy business model.

Bad ass shop

Great service

Ok

Great!

Very good place
