The process

How every car is tuned

01
Health check
Before anything changes, we scan the car for faults and log it exactly as it is. If something isn't right, you hear it from us first.
02
A calibration written for your car
Not a percentage added to a generic file. Every map is shaped by hand: a nice smooth boost map, not a square % change added to the corner.
03
Logged and refined on the road
We drive it, log it and refine it until the ECU and the engine agree. The log always gets the last word.
04
Your written report
Emailed to you: what your engine was doing before, what it's doing now, and the measured power and torque curves from your own car.

What you get

Proof, not "trust me"

Every tune comes with an ECU tuning report built from your car's own data: airflow, boost, fuelling, exhaust temperature and the measured curves, stock against tuned. Here's a real one, with the owner's details removed.

Drivability and longevity

Calibrated for how your car drives

Big numbers are the easy part to shout about. We calibrate for smooth, usable power right through the rev range, built to stay safe on stock hardware, so the car feels the way it should have left the factory and keeps feeling that way for years.

"We're not the cheapest and we're not trying to be. A cheap remap is a file flashed in five minutes with no checks and no proof. We do it properly, document it, and prove it's safe. That's what you're paying for, and that's why it lasts."
