What is a Stage 1 remap?
A Stage 1 remap is a software-only ECU tune for a standard vehicle, designed to improve power, torque, throttle response and drivability without requiring major hardware modifications.
Custom Stage 1 and Stage 2 remaps for drivers who want stronger performance, sharper response and a more engaging drive, with tuning selected to suit the vehicle and setup.
A Stage 1 remap is a software-only ECU tune for a standard vehicle, designed to improve power, torque, throttle response and drivability without requiring major hardware modifications.
A Stage 2 remap is for vehicles with supporting hardware upgrades such as intake, exhaust or intercooler changes. The calibration is matched to the vehicle’s setup.
Stage 1 is the best option for most standard vehicles. Stage 2 is more suitable when the vehicle already has appropriate supporting modifications.
