Growler Motor Labs

Expanded Scope


About Us

Why do customers travel from Ohio, Missouri, Arkansas, Nebraska, Oklahoma, Louisiana and all across the great state of Texas to visit our Plano location? Because Growler Motor Labs is the ultimate performance and prep shop in the Southwest. Formerly known as COBB Tuning Plano, and now owned by long-time COBB general manager Chris Fleming, we've earned a reputation as the most knowledgeable and experienced tuning company in the industry. For the past eight years, we've specialized in Porsche, BMW, Ford, Mazda, Mitsubishi, Nissan, Subaru and Volkswagen performance model vehicles. Now, as Growler, we've expanded our scope to service GM vehicles including Corvettes and Camaros with HP Tuners software and the Subaru BRZ, the Scion FR-S and Toyota FT-86 using EcuTek.

Ready to take your performance vehicle to the next level? Our team is standing by to help. When we deliver the finished product, you'll have a car you'll be proud to own...and can't wait to drive!



Today's import performance cars are beautiful, powerful machines, but they're capable of being modified to reach even higher levels of performance and style. Let our experts guide you through your options and help you set the proper goals for your vehicle. We'll steer you clear of sub-par parts and toward high quality components with a proven track record of delivering performance, quality and longevity.


Modern Engine Control Units are responsible for emissions, fuel economy, protecting drivetrain components and monitoring many sensors. Manufacturer calibrations of these ECUs are specifically designed to optimize stock configurations, making it easy to diminish your car's performance with even the simplest of bolt-on parts. Our certified tuners, using our on-site Mustang Dynamometer, will ensure that all components, both aftermarket and stock, work together in harmony to generate impressive power with high levels of safety and longevity.


Modified vehicles require vigilant maintenance. Changing oil, rotating tires, bleeding brakes, replacing coolant, maintaining filters and even checking tire pressures are important services that are essential to the lifespan of your performance car. Don't neglect your machine due to your busy schedule. Let the staff at Growler Motor Labs take care of all of your vehicle maintenance needs.


Pushing the limits will always expose the weakest link in your performance vehicle, but fixing the problem is only half of the solution. Finding a way to prevent the same failure from occurring again is the real challenge. Our ASE-certified technicians excel at failure analysis and will provide a quality-assured prescription to eliminate your problems. So when things go wrong, trust the experts at Growler to make them right again.


Whether you visit Growler Motor Labs in person to pick up the parts you need or prefer to shop our online store from the comfort of your home, you can trust that the products we offer are the finest on the market. As a Gold Certified Dealer, we prominently feature parts from COBB Tuning. We also sell premium parts from industry leaders such as Edelbrock, AMS Performance and Radium Engineering.


Need help deciding what's right for you? You can trust our experienced consultants to guide you through the chaos of the aftermarket wilderness and recommend top-quality parts proven to enhance performance. Call us at (214) 291-3020 for helpful suggestions, to check stock or to arrange for in-person pick up.

Mechanical Maestro

Barry Chappell oversees shop operations for Growler. A seven-year vet of our crew, he's the wrench-turning catalyst who keeps the operation humming with his broad base of technical skills, problem-solving instincts and team-first approach. Barry, a graduate of GM's ASEP Program and an ASE Master Technician, followed up his formal studies with 12 years of dealership experience. When it comes to exacting the best out of your car he's seen it all before...and he knows how to make it hum. When he's not in the shop, or busy shepherding his four kids to sporting events around DFW, Barry tries to find some time for his other passions: street bikes, dirt bikes and four-wheelers.

Performance Advisor

You can call him Isaiah, or you can call him Izzy...just make sure to call. When you do, you'll be able to take advantage of more than 15 years of industry experience and an uncanny knowledge of what it takes to make your car perform at its best. Prior to joining the Growler Motor Labs team, he honed his skills at three Subaru dealerships, Bobby Archer Enterprises and, most recently, LG Motorsports. Along the way, he's provided sales, service and trackside support to Corvettes, BMWs, Vipers, Camaros and Subarus, among others. It's that extensive background that gives him the know-how you can rely on when planning anything from simple performance upgrades to the most complex builds. A serial car buyer, Izzy drives a 2017 Challenger...although that may have changed by the time you read this. Stop by the shop today to take advantage of his expertise...or at least to see what he'll roll up in.


Kurt Nadeau joined us in 2017 and quickly earned a rep as an uncanny car whisperer. A top student at Lincoln Technical Institute in Grand Prairie, Kurt was promptly snapped up upon graduation by Toyota of Plano where he earned the coveted TMC Master Technician accreditation. After a five-year stint with the company, his passion for Subarus and other high-performance imports led him to our doors. He's made a fast impression with our crew and customers alike thanks to his tireless work ethic, his desire for professional growth and a dedication to quality craftsmanship that shines through in every car he services. When he's not enjoying some quiet time with his fiance, their two children and a rambunctious pit/lab/catahoula pup, Kurt enjoys wandering around local meets like Cars and Coffee and ECM.


Jaime Gonzalez is an emerging superstar on our team. A graduate of Universal Technical Institute, he's quickly established himself as an in-demand suspension and alignment guru. Whether your car is being prepped for the rigors of track day or is your daily driver on the PTA circuit, Jaime's expert attention will ensure it handles like a dream. Beyond that, his multi-platform versatility and team-first approach makes him a valuable contributor as we continue to add supported models.When he's off the clock, Jamie loves spending time with his kids, either hanging out at the park or playing soccer.


Grant Tillman has been a shop rat for as along as he can remember. The Houston native got his start at a local garage where he offered to work for free just to be around the cars. That informal apprenticeship allowed him to pick up a lot of skill the old-fashioned way and sparked a desire to pursue a more formal education. Grant first attended the School of Automotive Machinists, where he focused on engine cylinder head building, before moving on to EFI University where he received his certification in high-performance tuning. He spent two years building LS engines for Late Model Engines in Houston where his work caught the eye of COBB headquarters in Austin. When they heard we were looking for a high-end talent to join our team, they gave Grant their highest recommendation. After watching him work, it's easy to see why. He's quickly proved himself to be an expert at mining hidden horsepower, and brings an understanding of the domestic world that allows us to expand on our reputation for excellent tuning. Grant's passion for performance extends beyond his work in the shop. He's traveled extensively to attend some of the world's most challenging motorsports events, including Belgium for 6 Hours of Spa-Francorchamps and Australia for the Bathurst 12 Hour. He has his sights set on Germany for the epic 24 Hours Nürburgring event in the near future.


Al is Mr. Versatility around the shop, contributing cheerfully in a variety of functions. A former editor of Beckett Racing Monthly, his primary focus is on growing the company's social media presence and ensuring the Growler name becomes synonymous with excellence in the automotive community. Please direct media and advertising inquiries to his attention.
