Question 1

What’s the Difference Between Stage 1 and Stage 2/3?

Accepted Answer

Stage 1 is a software-only tune for a stock car in good health. Stage 2/3 is built around physical modifications (supporting hardware), and the tune is calibrated specifically to that upgraded setup.

Question 2

What’s the Difference Between Stage 2 and Stage 3?

Accepted Answer

Stage 2 is usually “bolt-on” upgrades (intake/exhaust/intercooler etc.) with a matching calibration. Stage 3 is a bigger build (often turbo/fueling changes) and needs a more bespoke approach with more testing and logging.

Question 3

What Hardware Mods Do I Need for Stage 2/3?

Accepted Answer

It depends on your car, but Stage 2 typically requires supporting airflow/cooling upgrades so the car can safely make more power. We’ll tell you what’s required vs recommended for your exact model.

Question 4

Can You Tune My Car if It’s Already Modified?

Accepted Answer

We can tune modified cars, but we’ll first confirm exactly what parts are fitted and check the car’s health. The tune is always matched to the current setup.

Question 5

Will This Fail My MOT / Emissions Test?

Accepted Answer

A tune alone doesn’t automatically fail an MOT, but mods and emissions equipment condition matter. We’ll advise on compliant options and what to expect based on your setup (and we won’t recommend anything that’s obviously going to cause problems).

Question 6

How Long Does a Stage 2/3 Tune Take?

Accepted Answer

Stage 2/3 usually takes longer than Stage 1 because it often involves more checks, more logging, and more fine-tuning. Exact time depends on the ECU type, the car, and the modification list.
