PORSCHE 991 TURBO/S TUNING
Litchfield Custom Tuning
991.1
We are able to recalibrate the Porsche 991.1 Turbo and Turbo S engine management systems directly through the On Board Diagnoistic (OBD) port and can increase power to 640 bhp on the standard car and to 670 bhp when using our titanium exhaust. Recalibrating the ECU takes around 2hours and customers have the option of performing before and after power runs.
991.2
Porsche 991.2 Turbos are fitted with a different ECU that requires unlocking prior to OBD tuning. The newer 991.2 engines feature revised billet compressor wheels on the turbos and can therefore produce higher power figures with standard cars increasing power to around 650 bhp and cars with our performance exhaust increasing to around 675 bhp.

Litchfield Titanium Exhaust
The Litchfield 991 Turbo/S exhaust system was extensively tested on our dyno and on the road to provide significant improvements in both performance and noise. This unique system is handmade in the UK by the same expert fabricator responsible for some of the very best F1 exhausts of this current era. We have specified the finest grade Titanium with beautifully crafted mandrel bends and tail trims to complete the exquisite look. High flow Catalytic converters from Germany use the latest emissions friendly coatings which also ensure compatibility with the engine management system whilst reducing exhaust back pressure.
Thanks to it’s titanium construction, our new exhaust has reduced the weight by approximately 16kg and liberates an extra 45bhp and 36lbft over the standard system, taking the car to nearly 600bhp without the need for ECU programming.
The throttle response and turbo spool are greatly improved due to the impressive reduction in back pressure. The exhaust note is transformed with a more aggressive bark under full throttle, crackling and popping on the over run for added theatre yet without being intrusive or droning when cruising.
Please specify, when booking, if your car is a 991.1 or 991.2 version as there are small differences in the systems. Both are a complete systems including catalytic convertors and take around 4 hous to install
