Cayenne Turbo Power Gains

Our Stage 1 calibrations for the 9Y0 Cayenne GTS are available for either 91 or 93 octane fuel and their increase over stock is truly astonishing. On 93 octane fuel, we are seeing 604 whp tuned compared to 519 whp stock and 684 wtq tuned compared to 530 wtq stock. This means you have an additional 155 lb-ft of torque on tap in the mid range along with an increase of 116 hp pulling you through the powerband.

Stage 1 93

Peak: +16.5% HP / Max: +29.1% HP

Peak: +28.9% TQ / Max: +29.4% TQ

Stage 1 91

Peak: +15.9% HP / Max: +25.7% HP

Peak: +25.4% TQ / Max: +26% TQ

Cayenne GTS Power Gains

The 9Y0 Cayenne GTS is mechanically identical to the Turbo model. Same motor, same turbos, and even the same ECU. The only difference between the two comes down to Porsche’s ECU logic as it’s strategy does vary slightly from that found in the Turbo. This means that while the GTS does benefit hugely from tuning, it does not *quite make the same power at the tire as that of the turbo post-tuning. The standard Stage 1 calibration file is available for both 91 and 93 octane fuel. On 93 octane, the GTS will make ~570 whp compared to 437 whp stock and 639 wtq tuned compared to 460wtq stock, an increase of 136 HP and 185 TQ over stock. Our “OEM+” file uses calibration data between stock and Stage 1, which provides the same power output as a Turbo model Cayenne and is compatible with either 91 or 93 octane.

Stage 1 93

Peak: +30.2% HP / Max: +40.5% HP

Peak: +38.8% TQ / Max: +41% TQ

Stage 1 91

Peak: +26.8% HP / Max: +35% HP

Peak: +33.3% TQ / Max: +35.5% TQ

OEM+ (91 or 93)

Peak: +28.1% HP / Max: +30.9% HP

Peak: +29.3% TQ / Max: +31.3% TQ

Cayenne S Power Gains

Porsche’s newer 2.9L Twin Turbo V6 powerplant responds very well to tuning! Our Stage1 tuning files produce a power band that is significantly smoother than stock while achieving significant increases to power under the curve. After touching right at 450 lb-ft of torque on 93 octane, we are able to carry impressive gains all of the way to the top of the power band.

Stage 1 93

Peak : +10% HP / Max : +28% HP

Peak : +15% TQ / Max : +28% TQ

Stage 1 91

Peak : +7% HP / Max : + 24% HP

Peak : +13% TQ / Max : +24% TQ

Cayenne E-Hybrid Power Gains

When people talk about the Porsche Cayenne E-Hybrid, the conversation usually revolves around fuel efficiency, battery range, and daily driving practicality—leaving raw engine performance as an afterthought. However, beneath that eco-conscious exterior lies a brilliant powertrain just waiting to be unlocked. With an Accessport tune, this hybrid sheds its sensible persona to deliver a level of fierce, relentless acceleration that will seriously stun anyone who still thinks hybrids are boring. Power gains on both 91 and 93 octane fuel are equally respectable.

Cayenne Base Power Gains

Included on the Accessport are two different versions of our Stage 1 Off The Shelf (OTS) Map. One is meant for use with 91 octane fuel, and the other with 93 octane fuel. The 93 map uses a higher boost ceiling which allows for better low end torque but the single turbocharger can’t efficiently hold that boost all the way through the gear so it drops at higher RPM. The 91 map uses a lower boost ceiling to control knock but this lower boost is more sustainable and the turbo can hold it a little longer. At the top of the gear, both maps are targeting the same boost but some runs can see slightly higher boost on the map that is less aggressive down low.

Stage 1 93

Peak: +11% HP / Max: +40% HP

Peak: +24% TQ / Max: +41% TQ

Stage 1 91

Peak: +12% HP / Max: +37% HP

Peak: +21% TQ / Max: +38% TQ
