Turbocharged petrol engines — the TSI, EcoBoost, and turbo units in most modern hot hatches and performance saloons — are superb candidates for tuning. A Stage 1 petrol map sharpens throttle response and adds real mid-range punch.
If your petrol car has a turbo, there's usually meaningful performance to unlock. We recalibrate boost, fuelling and timing within safe limits for a noticeably more responsive, quicker-feeling car — without touching a single component.
Naturally-aspirated petrol engines gain far less from a remap — often only a few percent — because there's no boost to optimise. We'll always be honest about what your specific engine will and won't gain before you commit.
Petrol maps are dyno-tested and developed through the Viezu network, your original file is backed up first, and remapping work carries an insurance-backed guarantee. Check your exact figures with our reg-based gains calculator.
