Porsche 911 Turbo / Turbo S (991.2) ECU Tune
$2,699.00
Product Description
For the 991.2 refresh, Porsche went further still, fitting the Turbo's 3.8-liter six with larger variable-turbine-geometry turbochargers, reworked compressors, and revised intake ports. The Turbo S got its own bespoke upgrade on top of that, with larger turbo impellers and a modified housing enabling a higher redline. The payoff was factory output climbing to 540 hp for the Turbo and 580 hp for the Turbo S, with quicker spool and a noticeably sharper response than the already-impressive 991.1 it replaced.
Weistec's calibration builds on that revised turbo hardware rather than working around it, recalibrating boost and timing to the same rigor Porsche applies to its own factory software while leaving knock protection, thermal management, and OEM diagnostics fully intact. On this platform the tune is worth a substantial 110 hp and roughly 120 lb-ft, unlocking headroom those larger factory turbos were built to support and turning a genuinely quick car into a seriously fast one.
