Does this ECU tune fit all 991.2 Carrera trims?

Yes, the Fabspeed 991.2 Carrera ECU tune is calibrated for 2017-2019 Carrera, Carrera S, and Carrera GTS models with the 3.0L twin-turbo flat-six. Power gains differ by trim: Carrera sees the largest increase, followed by Carrera S and GTS. The handheld tuner is programmed for your specific vehicle at installation and cannot be transferred to another car afterward.

How does the Fabspeed XperTune 991.2 Carrera ECU tune install?

Installation uses a handheld tuner and a Windows PC connected through the OBD-II port, so the factory ECU never leaves the car. The software reprograms sensor inputs, air-fuel ratios, and boost pressure to unlock additional horsepower and torque. A Windows PC is required for the initial setup; Mac computers are not supported for this process.

Can I install this 991.2 Carrera ECU tune myself?

Most owners install it themselves in under an hour using the included handheld tuner and a Windows laptop, with no special tools or shop visit required. The process walks through the OBD-II connection step by step, and the tuner can flash the car back to its factory calibration at any time if needed.

Can I revert to the factory tune after installing this ECU software?

Yes, the same handheld tuner that installs the 991.2 Carrera ECU tune can flash the car back to its original factory calibration at any time. This makes it easy to return to stock for dealer service, warranty visits, or resale without needing to ship the ECU anywhere.

How much horsepower does the Fabspeed XperTune add?

Gains vary by trim: the 991.2 Carrera picks up roughly 115 horsepower and 150 lb-ft of torque, the Carrera S about 90 horsepower and 110 lb-ft, and the Carrera GTS around 75 horsepower and 80 lb-ft. These figures reflect improvements over stock on a properly maintained, unmodified engine.

Does this ECU tune affect my factory warranty or come with support?

Because the tune can be reversed back to the factory calibration at any time, it can be temporarily removed before dealer service if you have concerns about warranty coverage. Fabspeed backs the 991.2 Carrera ECU tune with ongoing phone and email support for setup questions after purchase.

Fabspeed XperTune 991.2 Carrera ECU Tune Software

The 991.2 Carrera ECU tune from Fabspeed’s XperTune Performance Software reprograms your factory ECU through the OBD-II port without ever removing or shipping the unit. Fabspeed Motorsport introduces an innovative tuning solution for vehicles equipped with ECUs that traditionally required bench flashing. There’s no need to go through the hassle of removing and mailing in your ECU anymore. The handheld device seamlessly interfaces with the OBD-II port in their vehicle and computer to complete the tuning process. By simply flashing their 991.2 Carrera / Carrera S with a Fabspeed ECU Tune using the provided handheld tuner, they can experience improved horsepower, torque, and driving characteristics. This is achieved through the reprogramming of various sensor inputs, air/fuel ratios, and boost pressure (if applicable). Fabspeed offers a range of maps suitable for completely stock cars or those equipped with race pipes, sport cats, full exhaust systems, upgraded turbos, and more.

Notes

While a vehicle equipped with bolt-on upgrades will experience maximum gains as a result of the increased efficiency of the engine, great power gains can be made on a completely stock vehicle
You must have access to a PC / Windows computer (Mac OS not supported) to upload new tune files or reset back to stock with your handheld device
The Handheld device “marries” with your vehicle and can only be used on one vehicle
Special requests and tune file upgrades may be subject to additional fees
No need to send your ECU in to return to stock – simply use the Handheld to flash back, then to your Fabspeed XperTune again at any point

Additional Information

The Bulletproof Automotive website contains many thousands of products purchased in multiple different currencies. All of the prices are entered manually and accurately at the time of entry. Due to the consistently fluctuating international exchange rates, at times prices may not be able to be honored at their original intended rate. We apologize for any inconvenience this may cause, unfortunately our website is unable to compensate dynamically for what can at times be volatile changes in the cost of items due to currency values fluctuating, changes in prices from suppliers, changes in shipping and import duties, and other factors. Rest assured that any order you place on line will be at zero risk to you in this area. If in the event your order cannot be fulfilled at the original intended website price we will offer you a 100% refund, no questions asked. We will continue to do our best to maintain updated prices and we will always continue to offer our price match guarantees as well to ensure our prices are always the best for you. In short, prices may change without notice. It is always advised to give us a call prior to placing your order online to confirm availability and to confirm current pricing.

Shipping Policy

Items that are in stock in the US, either at Bulletproof’s warehouse or at a supplier’s warehouse, are generally delivered within 7-10 days. Special order items from overseas take considerably longer. As a courtesy Bulletproof offers delivery estimates to our customers which take into consideration manufacturer availability and shipping schedule. These estimates represent our best guess based on previous orders from the manufacturer and do not in any way imply a guaranteed delivery window. Many manufacturers work in a “just in time” inventory system and often take 2-20+ weeks to produce an item once an order is submitted. All deliverable items are then sent to our Japanese warehouse. Bulletproof ships a minimum of one full ocean freight container every month from Japan, oftentimes more than one a month. Ocean freight takes an average of 4 weeks. Typically it breaks down to one week in Japan for paperwork and customs, two weeks by boat and one week in US customs/clearance. Due to the wide number of variables between manufacturer and shipping schedules, delivery estimates are simply just that – estimates. We attempt to estimate conservatively and we usually deliver faster than our estimates suggest. It is not Bulletproof’s policy to guarantee delivery time of any special order item, this is impossible for us to do. By ordering you acknowledge that there is no required delivery ETA and an order may not be canceled or altered due to manufacturing or shipping delays, all ETA’s are provided as a best guess only. Please review the full Terms & Conditions here.

BP Pricing Difference

We do pricing a little differently on our JDM brands and we believe in making things simple and clear. No hidden fees or surcharges. Every price you see includes the shipping cost to our office in Los Angeles, California and all the associated taxes/duties/fees for bringing the products into the US. The only shipping you ever pay is from our facility in the US to your location. Be wary of resellers that don’t include the cost of international shipping in their pricing on JDM parts. While we believe we’ll always have the lowest all-in price on JDM products, we offer a price match guarantee for all authentic parts purchased from authorized dealers as well. For many international customers, it’s much more affordable to ship from the USA than from Japan directly, as the air freight and ocean freight costs are typically much less. However, for customers looking to ship directly from Japan outside of North America, or domestically in Japan, we can provide pricing specifically for that scenario. Please do not hesitate to contact us with any pricing questions or concerns. Please email us at sales@bulletproofautomotive.com with any inquiries.
