The DEFI Global Tuning Network
Work with the dyno, not around it
Performance has no borders, but measurement has to happen somewhere. We connect shops, calibrators and manufacturers to a 3,400 hp hub dyno in Corona, California — and to a calibration practice that publishes its conditions.
What a partner gets
Four things this shop can do for another business
All of it is available today, on equipment already in the building. Nothing on this page is a description of something we intend to buy.
Validation on a hub dyno
Part manufacturers get a 3,400 hp Mainline ProHub and a full sheet with the conditions on it. A claim measured on a hub is defensible in a way a roller number is not — that is worth something when a customer challenges it.
Calibration support for shops without a tuner
Mechanical shops that do good work and do not want to employ a calibrator send us the car, or the file. We do the tune, you keep the customer. We do not solicit your customers afterwards.
Cell rental with an operator
Travelling calibrators book the cell and run their own laptop and their own licenses. We mount, cool and capture. You keep your process.
A route to a Southern California market
Products that need a demonstration rather than a description do better in front of people who drove to a dyno on purpose. Group days and club events put them there.
Platforms we tune
Eight management systems, and the factory ECU
We tune factory controllers across 33 makes through HP Tuners, and standalone management on the platforms below. These are systems we run, not badges we display — we do not claim a certification from a vendor that does not issue one.
- HP Tuners
- Holley EFI
- MoTeC
- Link ECU
- Haltech
- FuelTech
- Emtron
- ProEFI
Who this is for
And who it is not for
Performance shops
You do the mechanical work and want a calibrator you can hand a car to without losing the customer.
Independent calibrators
You need cell time on a hub dyno in Southern California, with an operator who knows the equipment.
Part manufacturers
You need a defensible before-and-after on a machine that measures the same way twice.
ECU and software vendors
You want your platform in front of a shop that will actually learn it properly.
If you are buying a tune for your own vehicle, this is the wrong page — find your vehicle instead, or book the dyno.
