Unlock the full potential of the turbo-charged 1.4 TSI EA111 engine in your VW Golf V GT with this checksum-corrected MED17.5.1 calibration package. The bundle delivers a clean Stage 1 power hike, removes the factory Vmax limiter and adds selectable pop-and-bang exhaust burble in Sport mode — all while preserving OEM safety strategies for knock, EGT and lambda. Every map area is hand-refined in WinOLS: torque structure, load-to-boost conversion, ignition advance and fuel targets. Flash-ready via OBD, bench or boot with bFlash, FLEX, KT200 or any MED17-capable tool. Original stock file included for hassle-free rollback.
