Performance Work.
Whether it's bolt-on upgrades, fuel system overhauls, or full power builds — HD Garage handles the work that turns stock cars into something serious. Done in-house, dialed in by people who actually drive what they tune.
What's Included
- Bolt-on power packages (intake, exhaust, intercooler, charge pipes)
- Fuel system upgrades — port injection, methanol, E85 conversion
- Turbo upgrades — twin upgrades or single conversions
- Custom dyno tuning to dial in the build
- Supporting mods for big power (clutches, axles, cooling)
- Full performance diagnostics before and after work
Who It's For
- BMW M & S series owners wanting more out of their platform
- Built engine owners adding the right supporting mods
- Customers chasing a specific HP target with a proven build path
- Anyone tired of "tuner shops" that don't actually know the platform
