Dynojet 424XLC
AWD dyno testing & rental
Power numbers matter. So does understanding what the car is doing under load.
Our Dynojet 424XLC AWD dyno uses eddy-current load control. We can apply controlled resistance during a session and review how the vehicle responds, alongside its horsepower and torque. It's a useful part of understanding a setup and checking the changes made to it.
Ask us about baseline runs, before-and-after testing, tuning sessions or dyno rental. Send your vehicle, drivetrain, current setup and what you want to learn so we can confirm the session requirements and availability. Vehicle health comes first. A car may arrive with existing modifications, an unknown tune or unresolved problems from a previous build. We check its condition and address the issues that need attention before load testing. When a baseline pull is not safe, we document the work and final tested result without claiming an unmeasured horsepower gain.
Engine & drivetrain
ECU, TCU & CPC calibrations
The right calibration starts with your car: its hardware, fuel, current software and how you drive it.
- ECU calibration for the engine and its supporting modifications.
- TCU calibration for supported transmission applications.
- CPC calibration where supported by the vehicle and software.
On supported platforms, we offer bench and boot work, ECU/TCU unlocks and remote calibration options. Availability depends on the control unit and software version.
Tell us the year, make, model, engine, modifications and fuel you plan to use. We'll confirm compatibility and discuss the calibration your setup needs before moving forward.
Unlock more with your tune.
In-house ECU unlocking
Tune with BoostedJunkie and get a complimentary ECU unlock.
Book a qualifying BJG tuning service and your supported ECU unlock is included at no additional charge. We unlock supported ECUs in-house—no shipping required. Support includes Mopar GPEC2, GPEC2A and GPEC4; BMW and Toyota Supra A90 ECUs; GM E90 and E41; and many more.
Send your year, make, model and VIN so we can verify your exact vehicle and ECU. We’ll confirm compatibility, tuning options, the total package price and expected turnaround before booking. Complimentary unlocking applies to supported ECUs with a qualifying BJG tune; standalone unlocking is a separate service.

Custom exhaust & fabrication
Tell us how you want it to sound, what needs to fit and what the car is built to do.
We work with stainless steel, titanium, aluminum, chromoly and mild steel. From a custom exhaust to fabrication that supports the rest of your build, we'll discuss the material, fit and scope with you.
Looking for a BJG exhaust or a part for your platform? Browse our parts, or send photos and vehicle details if your project needs something custom. We can also discuss installation and the supporting upgrades your setup calls for.

Diagnostics, maintenance & repair
Keep your maintenance close to home. Before you plan a long dealership trip, call us with your vehicle and the service it needs.
Oil and filter service, brakes, plugs and coils, cooling-system work, fluids and leak repairs all belong in the conversation. We'll confirm what we can handle here so you can plan your time and budget before making the trip.
Check-engine light, misfire, boost leak, overheating, electrical issue or something that just doesn't feel right? Tell us when it happens, any fault codes and what's been changed recently. Those details help us plan the diagnostic work your vehicle needs.
