Hemituner Performance

What Hemituner Performance does

Hemituner Performance (legal entity HEMIFAST) is a privately held, founder-owned specialty automotive performance company founded in 1997 and headquartered in West Babylon, NY. The company exclusively serves the Gen 3 Hemi platform market, offering custom ECU calibration and tuning, high-performance HEMITUNER 1250/1550/1650 426 HEMI crate engines developed over 15+ years, live dyno calibration services using Dynojet and Mainline Prohub 6000 equipment (up to 6000 HP), and HEMIFAST Racing Support programs including team management for drag racers. Pricing is quote-based and not publicly disclosed.

The business operates on a dual revenue model combining hardware sales (crate engines, performance parts via e-commerce storefront) and professional services (custom tuning, dyno calibration, racing consultation). The company targets two primary segments: competitive drag racers seeking maximum power and reliability, and Gen 3 Hemi vehicle owners (Dodge Charger, Challenger, etc.) seeking performance modifications. Distribution is direct-to-consumer through an online store and phone-based consultation, with GTM relying on earned media coverage in Dodge Garage, Dragzine, Mopar Connection Magazine, HotCars, and 1320Video, plus organic Instagram presence.

The company is led by President AJ Berge, who has over 30 years of factory-certified Chrysler technician experience and remains hands-on in shop, dyno, and track operations. The business is bootstrapped with no external funding, no disclosed institutional investors, and 1-10 employees. Notable racing achievements include the 2022 Norwalk Drag Pak win and 2023 NMCA season opener win under the Ramchargers banner, providing the validation backbone for the company's claims of racing-proven expertise.

Direct peers

• Arrington Performance: Closest comparable: also manufactures crate engines (Hellephant, Challenger/Demon performance engines) and offers tuning/calibration services targeted at Gen 3 Hemi and Mopar platforms, with a similar specialty-shop business model.
• HP Tuners: Major aftermarket ECU tuning platform and calibration provider for a broad range of vehicles including Chrysler/Hemi; competes directly with Hemituner's tuning service offering and also supplies the tools many tuners use.
• DiabloSport: Established aftermarket performance tuner offering handheld tuners, custom calibrations, and performance products spanning multiple vehicle brands including Dodge/Chrysler; directly competes in the same tuning and parts space.
• BES Racing Engines: Custom race engine builder specializing in high-horsepower engines for drag racing applications, with comparable build/validation processes and target customer (drag racers and performance enthusiasts).
• Modern Muscle Automotive: Specialty performance shop focused on late-model Mopar/Chrysler vehicles, offering parts sales, tuning, and dyno services — directly overlapping with Hemituner's customer base and product categories.
• Lund Racing: Performance tuning shop offering custom ECU calibrations and remote tuning services across multiple platforms; comparable service-led business model and customer segment (enthusiasts seeking professional calibration).

Broad incumbents

• Edelbrock: Long-established major aftermarket performance parts manufacturer offering engine components, intake manifolds, and crate engines across many vehicle platforms; overlapping category but much broader portfolio than Hemituner's Hemi-only focus.
• COMP Cams: Major manufacturer of valvetrain and engine performance components used across drag racing and street performance; adjacent product overlap with Hemituner's crate engine development work, but operates at far greater scale across multiple platforms.
• Holley Performance: Diversified performance aftermarket company offering EFI systems, engine components, and branded performance parts (including MSD, ACCEL, Hooker); competes in adjacent product categories with vastly broader scale and brand portfolio.

Others

• Summit Racing Equipment: Largest mail-order and online retailer/distributor of performance parts; not a direct competitor on tuning services, but a key channel/ecosystem participant where Hemituner customers purchase complementary parts.
