Porsche 991.2 Carrera

The Porsche 911 is a performance icon and in the latest 991.2 variant offers both incredible levels of performance and refinement. With the switch to all 3.0 Litre turbo charged engines there is significant opportunities to improve this performance. We have our own 3.0T development vehicle in the form of our Carrera T so we will be producing the very best engine, chassis and cosmetic options for all of the 991.2 Carrera models.

Litchfield OBD Custom Tuning



We offer a fully re-calibrated engine management system, providing a significant increases to both power and torque. This customised ECU mapping releases considerably more power than standard or ‘off the shelf tunes’ and allows us to create a really smooth, driveable car. The process is straight forward and requires the ECU to be unlocked and then tuned though the OBD port which offers fast programming or reverting back to standard.


We have invested in our own 3.0T powered 991.2 so we have been able to fine tune the calibration on our Maha Dyno (the same used by Porsche) but more importantly we are living with our setup day to day on both the road and track. We feel we have developed the ultimate software upgrade for the 991.2 turbo engine.


All the current 3.0 Turbo engines are the same except for the turbos themselves; the Carrera S uses a slightly larger compressor wheel and the GTS uses both a larger compressor wheel and turbine wheel to increase power.


Our software upgrade for standard 911.2 Carrera models provide the following increases when using Shell Vpower:


Model Power Torque
Carrera and Carrera T Standard 365 bhp (370 PS) 332 lbft (450 Nm)
Carrera and Carrera T Litchfield Remap 454 bhp (460 PS) 400 lbft (542 Nm)
Carrera S Standard 414 bhp (420 PS) 369 lbft (500 Nm)
Carrera S Litchfield Remap 463 bhp (470 PS) 420 lbft (600 Nm)
Carrera GTS Standard 444 bhp (450 PS) 3406 lbft (550 Nm)
Carrera GTS Litchfield Remap 512 bhp (520 PS) 479 lbft (650 Nm)

The hardware changes can be installed to improve performance on their own but when combined with our ECU recalibration the increases are even greater. We will be developing a number of hardware upgrades to further enhance the 3.0T performance.

991.2 Exhaust Options



We offer a number of exhaust options to suit the each customer’s requirements. The standard Porsche 3.0T exhaust is very restrictive and relatively quiet, even with the popular ‘Sports Exhaust’. The options below solve this problem and provide tangible improvements in both engine performance, weight saving and exhaust note character. Both the Remus and Akrapovic rear silencers can be installed easily and require no changes to the standard ECU calibration.




Remus Sport Label Rear Silencer





Austrian exhaust manufacturer Remus are OE suppliers to Porsche (they currently make the Sport Exhaust tail trims for the factory) as well as BMW and Mercedes, so their quality is guaranteed. Remus offer a Sports Label rear silencer for the 3.0 T, which gives a small power increase, but a huge improvement in noise with a deeper more menacing exhaust note. The Remus silencer is designed to simply replace the original Sports Exhaust and utilise the original OE tail trims and exhaust valve control. Customers looking for a subtly different appearance can choose the optional Carbon and titanium tail trims.

Akrapovic Slip On Line Titanium Exhaust System



Akrapovic are the world leader in titanium exhaust systems and are featured on everything from MotoGP winners, LeMan LMP Audis to the most converted supercars. Akrapovic even produced the titanium exhaust system for the original Porsche GT3 RS. We are proud to say we are Akrapovic’s largest UK dealer and have even helped develop some of their newer systems.


Slip On Line with Link Pipes




For the 3.0T engine Akrapovic offer solutions to suit both the standard and Sports exhaust options. The power gains and weight saving is significant over the original systems but the Akrapovic system has also been tuned to give an aggressive tone and increased overrun theatre when pressing on whilst still remain cultured and smooth sound on a motorway cruise or with the valve closed.


The Akrapaovic Slip-on Line is made from their own propriety Titanium and reduces weight by over 35% and provides a power increase of +19 bhp and +28.5 lbft! For those customers looking for the ultimate setup Akrapovic also offer Sport CAT link pipes that further improve the exhaust gas flow and aural quality. When combined with the Slip-on Silencer the power increases by +23bhp and 33.9lbft, incredible increases from just an exhaust and an example of how restrictive the OE system is. Even greater gains are available when combined with our ECU remap.


The Slip-on rear silencer is finished with titanium rear tail pipes and can be further enhanced with the addition of Akrapovic rear carbon diffuser (available in Matt or Gloss Carbon finish).
