Justin's own cars are a 6.87 at 200 mph Mustang and a 1,654 horsepower 2020 GT with a baby seat in the back. Coyote Mustangs are not a sideline here, they are the reason the shop exists.
2011 and newer Mustang GT, EcoBoost, GT350, GT500 and the new S650. From a first set of bolt-ons to a sleeved block and twin turbos, planned as one combination and proven on our own dyno before you get the keys back.
We sell what is bolted to Justin's own car. Hellion, Whipple, Circle D, Fore Innovations, Injector Dynamics, Kooks, BMR and Kelltrac are all on the brand wall because they are all under his hood.
Intake, throttle body, long tube headers, exhaust, and the custom dyno tune that makes them work together. The honest first step for a stock GT.
Whipple Gen 6 Stage 1 and Stage 2, Roush and VMP. Installed with the fuel system and cooling to actually hold it, and calibrated here on the fuel you run.
Hellion dealer. Sleeper and Eliminator twin turbo kits, single turbo setups, and the fuel, oiling and tuning work that decides whether a turbo car lives.
Oil pump gears, cam phasers, timing components, clutches, rear ends, 10R80 work with Circle D converters. The jobs that keep a fast Mustang from becoming a slow one.
Starting prices for jobs we do every week, straight out of ShopMonkey and rounded down. Every quote is written for your car with the labor shown as its own line, so you can see exactly what you are paying for.

"I was looking for someone to tune my 2013 Mustang GT and as soon as I saw coyote specialty I knew I'd want to give them a shot. Spoke back and forth with Justin for a while and was able to have them repair my car and tune it. My car feels amazing! More responsive and running great. I can't thank Southern Performance & Justin enough."
"Justin tuned my 2018 mustang gt back in the day and knows his stuff!! I was having issues with my car and decided to take the 2hr drive up to Orlando to go see them because I knew I'd be in good hands. If you want a reliable and trustworthy place to take ur vehicle go straight to southern performance."
Tune it. A custom dyno tune on a stock Coyote is the best money you will spend on the car, and it is the baseline everything else gets measured against. Headers and an intake come next. A blower comes after the oil pump gears, not before.
On a 2011 to 2025 GT, yes. The factory gears are powdered metal and they are the known weak point once boost and rpm go up. We will not sell you a blower without telling you this first.
Usually, and we will tell you if a part is wrong for the combination before it goes on. Parts we supply carry our warranty support; customer parts carry the manufacturer's.
All over Central Florida. Plenty of customers drive over from Tampa and the coast for a tune or a build, and the reviews above are two of them.
Yes. Voodoo, Predator and the 2024 and newer Coyote all come through the shop, along with EcoBoost cars.
Year, what is on it, and what you are chasing. We will price it properly and tell you the order to do it in.
