Frequently Asked Questions
Do I need any modifications for Stage 2 tuning? Yes — Stage 2 typically requires supporting modifications such as intake, exhaust, or intercooler upgrades. We’ll advise you on exactly what your vehicle needs before proceeding.
Will remapping affect reliability? When done correctly, no. Our approach focuses on safe, reliable performance gains, not pushing components beyond their limits.
How long does a remap take? Most Stage 1 remaps take 1–2 hours, including diagnostics and testing. More complex setups or Stage 2 tuning may take longer depending on the vehicle.
Can you come to my home or workplace? Yes — we are fully mobile. We cover Norfolk, Suffolk, and the wider East Anglia area, meaning your vehicle can be tuned at a location convenient for you.
Do you use generic files or custom tuning? We do not use generic “flash and go” files. Every vehicle is assessed first, and tuning is carried out based on your vehicle’s condition and setup.
How much power will my car gain from a remap? Every vehicle is different, but most Stage 1 remaps typically see gains of 20–40% in power and torque, along with improved throttle response and drivability.
