For the last few percent — or for heavily modified vehicles — nothing beats live tuning on the rolling road. We map the vehicle in real time under load, log the results, and prove the gains with a printed power run.
Power run from £60
A rolling-road power run session measures your actual power and torque at the wheels — the honest before-and-after that a laptop alone can't give you.
Live steady-state mapping
Available for many OEM ECUs, live tuning lets us optimise fuelling and boost across the whole map under real load, not just to a template.
Full data acquisition
Our 2WD dyno logs air/fuel, boost, temperatures and more so every change is measured, not guessed.
Diagnostics included
We health-check the vehicle before we tune and re-scan afterwards, so you leave with a car that's both faster and running clean.

Good to know
Common questions.
Can you live-tune my car?+
Live tuning is available for some OEM ECUs — it depends on the vehicle. Contact us with your make, model and any modifications and we'll confirm.
What does a power run cost?+
A rolling-road power run session is £60. If you go on to have tuning done, that's quoted based on the work involved.
Do I need a power run with a remap?+
Not for a standard Stage 1 road remap, but it's the best way to verify gains or to develop a custom map on a modified vehicle.
