Stage 1 mapping focuses on earlier boost and smoother low-gear pull, while the optional Stage 2 file extends the same logic after removing DPF routines entirely. Both variants zero EGR flow, raise torque / boost / smoke ceilings and realign throttle maps so the five-speed super-mini feels markedly livelier in daily traffic yet cruises with stock-like economy. Cold-start, idle and light-load areas are refined so manners stay factory-smooth even when the physical DPF is taken out.
