Porsche Boxster (2016 - 718) 2.5T (S) 350 hp — sports petrol engine of the passenger segment of the Volkswagen Group (VAG) group (Германия, 1931). Stage 1 chip tuning raises power from 350 to 400 hp (+50 hp, +14%) and torque from 420 to 500 Nm (+80 Nm). The 2016 generation — mid-generation petrol ECUs (MEDC17/MEVD17/Simos PCR), OBD flash on production revisions.

Porsche specialises in sports cars, roadsters and premium SUVs. Porsche has been part of the Volkswagen Group (VAG) since 2012. Porsche is a premium sports car manufacturer from Stuttgart-Zuffenhausen, founded in 1931. The GT3 / GT2 RS form a calibration segment of their own. Top-tier Porsche Turbo engines have significant potential with a downpipe + intake. The factory Porsche calibration is sporty, yet there is still headroom for Stage 1.

With a downpipe + intake, top-tier Porsche Turbo engines comfortably reach Stage 2. Within the VAG group, Porsche shares some ECUs and platforms with Audi. On pre-2017 Porsche models, Stage 1 is done via OBD without bench. Top-tier Porsche engines (Turbo S, GT3, GT2 RS) sit at the brand's power ceiling; the gain is significant. Porsche engines are a proven base once supporting hardware is added. A Bench read is standard procedure on modern top-tier Porsches.
