Before you book
Frequently Asked Questions
What is an ECU Stage 1 tune?
Stage 1 is a software calibration designed to improve usable power, torque and response while working with the standard or approved lightly modified hardware for the vehicle.
Can the tune be installed in one day?
Same-day installation is available for many eligible Stage 1 vehicles. ECU unlocking, unusual software, diagnostic faults, supporting hardware or custom dyno work may require additional time.
Does Stage 1 require additional hardware?
Many Stage 1 applications do not require major hardware changes, but requirements vary by vehicle, engine and calibration. Any required parts will be confirmed before installation.
What fuel should I use after tuning?
Use the fuel grade specified for the selected calibration. Harrys Euro will confirm the required octane and important fuel guidance for the exact vehicle.
Will tuning affect reliability?
Performance tuning increases demand on some vehicle systems. Vehicle condition, servicing, correct fuel, suitable hardware and an appropriate calibration all matter. Known faults should be repaired before tuning.
Can the vehicle be returned to factory software?
Returning to factory software is possible for many applications, but procedures, software history and warranty implications vary. Ask Harrys Euro about the exact vehicle before proceeding.
Does my ECU require unlocking?
Some ECUs require an additional unlock process. Harrys Euro will check the vehicle and ECU details and explain any extra cost, removal or turnaround time before work begins.
Do you offer DSG or other transmission tuning?
Compatible DSG and other TCU tuning options are available for selected vehicles. Availability and recommended combinations depend on the transmission, engine calibration and intended use.
Do you offer Stage 2, Stage 3 or custom dyno tuning?
Yes. Higher-stage and custom dyno options are available for selected vehicles, subject to suitable hardware, fuel and vehicle condition.
