Stage 1 appears early in this file set, followed by Stage 2, each broadening the 1.4 Turbo’s usable torque band while keeping OEM smoothness. DPF is not fitted, but all EGR functions are disabled for a cleaner intake. Boost, load and torque limiters are lifted with conservative ignition tables so the six-speed driveline stays within factory margins. Cold-start, idle and part-throttle areas are retuned for stock-like fuel economy, yet boost builds noticeably sooner for livelier city driving and effortless highway merging.
