What we do
Diagnostics
Tell us when it happens, any fault codes and what has been changed recently.
BJG Health Checks
Pre-purchase inspections and checks before we add power.
ECU tuning
The right calibration starts with your car: its hardware, fuel, current software and how you drive it.
Custom exhaust & fabrication
Tell us how you want it to sound, what needs to fit and what the car is built to do.
AWD dyno
Ask us about baseline runs, before-and-after testing, tuning sessions or dyno rental.
Calibration and unlocking support depend on the control units and software versions. We confirm compatibility before moving forward.
Dyno-proven results
Results from complete tested configurations. Gains are shown only where a recorded baseline exists.

From the garage
Before your visit
What details do you need about my Porsche?
Send the year, model, engine, mileage, modifications, fuel and what you want to solve or build.
Can you check the car before adding power?
Yes. Book a BJG Health Check so we can look over your car before planning loaded dyno runs.
Does every result include a measured gain?
We only show a gain when we measured the car before and after. If we only have a final run, we show that result on its own.
How do I confirm service or installation?
Tell us what you drive and what you want done. We’ll check what fits, talk through the work and confirm an available appointment.
Where is the garage?
