Is stage 1 or 2 tune better?
Due to the increased power and additional modifications, stage 2 remaps can provide much larger power gains than stage 1 remaps. In general, you can expect a power increase of around 30-50%, which will significantly improve your car’s performance. A stage 3 remap is the most extreme form of engine tuning, and it should only be carried out by experienced professionals. Stage 3 remaps involve significant modifications to the engine, turbocharger, and intercooler, and they can result in power gains of over 50%.
