Porsche 992 Turbo S — The 9A2 EVO PlatformThe Porsche 992 Turbo S is powered by the 9A2 EVO (MA1.xx) — a 4.0-litre twin-turbo flat-six that produces 640 HP and 590 lb-ft of torque from the factory. It is one of the most capable forced-induction engines in any production sports car, with a power-to-displacement ratio that puts it among the most energy-dense road-car engines ever built.The 9A2's engineering margin is substantial. Porsche builds this engine for the kind of sustained abuse that 911 Turbos have always been subjected to — which means there's significant headroom above stock calibration that an...

Ferrari 488 GTB — The F154 Twin-Turbo V8The Ferrari 488 GTB marked Ferrari's return to forced induction in its mid-engine V8 lineup. The F154 3.9-litre twin-turbo V8 replaced the naturally aspirated F136 from the 458 Italia — and with it came a platform that responds extremely well to ECU calibration.Where the 458 had limited tuning headroom as an NA engine, the 488's turbochargers give calibrators room to work. A well-written ECU tune extracts meaningful power without touching internal components.→ Browse all Ferrari performance partsF154 Engine Specifications Spec 488 GTB 488 Pista Engine Code F154CB F154CD Configuration 3.9L Twin-Turbo V8 3.9L...

BMW M4 G82 S58 Engine — The PlatformThe BMW S58 is a 3.0-litre twin-turbo inline-six and the heart of every G-chassis M car: M4 G82, M3 G80, M2 G87, X3 M, and X4 M. In Competition spec it produces 503 hp and 479 lb-ft of torque from the factory — but with a closed-deck block, forged crank, and twin mono-scroll turbos, it was built to handle significantly more.That headroom is why the S58 has become one of BMW's most tuned modern engines. A well-calibrated ECU flash can unlock serious power without opening the engine.→ Browse all BMW M performance partsS58...

The Ferrari 488 GTB rewrote the rules for mid-engine Ferrari performance when it launched in 2015. Replacing the naturally aspirated 458 Italia with a 3.9-liter twin-turbo V8 (Ferrari engine code F154), it delivered 661 HP and 561 lb-ft of torque — numbers the NA predecessor couldn’t touch. The Pista variant pushed that to 710 HP. And unlike naturally aspirated Ferraris where ECU tuning yields modest gains, the 488’s turbocharged architecture responds dramatically to recalibration.YPG Motorsport has tuned Ferrari 488s since 2017 — including our own Stage 2 488 GTB that ran at Kuwait Motor Town.
