Whether you are looking for a modest improvement or a dramatic increase to power, torque and handling, Swallows Racing is the place to come for JLR tuning that offers a better and more rewarding driving experience.
Working with some of the industry’s best brands as well as designing our own performance products in house our products are helped by honing and setting up our cars from our extensive racing program, meaning all knowledge is reverse engineered back to our customers road cars from 1000’s of hours of data analysis and driver feedback.
We offer a number of different stages in each area designed to push the performance of the JLR models, However if you have an exact goal in mind then stages can be tailor made to your requirements – Contact us for more information on how we can achieve your dream.
Stage 1 / 440BHP
– Our Stage 1 upgrade brings out the full benefits of the Upper charger pulley and incorporates a recalibration of the engine management system along with a high flow air filter to compliment the intake efficiency. This recalibration releases significantly more power and transforms the way the engine performs, without pushing the limits of JLR’s original engine parameters.
The Stage 1 Power upgrade includes:
: SR 7% upper supercharger pulley
: SR/ Pipercross high flow panel filter
: Reduced fuel consumption (especially on partial throttle conditions)
: Increase in both power and torque across the whole rev range
: Revised ignition control, variable valve timing and fuel maps
Stage 2 / 445BHP

With custom pedal box and short shifter you are fully in control, making the driving experience like nothing else and ready to tame every B road. Lightened Billet flywheel and TTV race clutch plate/cover not only reduce rotational mass but shorten gear changes with sharp and firm gear changes when you are pushing the car further.

: SR 7% upper supercharger pulley
: SR/ Pipercross high flow panel filter
: Reduced fuel consumption (especially on partial throttle conditions)
: Increase in both power and torque across the whole rev range
: Revised ignition control, variable valve timing and fuel maps
Stage 3 / 445BHP
– Stage 3 Removes the restriction from OEM Catalytic Convertors from 900 cell count down to 300, this allows us a bring in power a little earlier and create a little more at the top end, adding sports cats in the stage 3 package gives a noticeable increase in performance and noise. 300 cell sports cats retain UK MOT emissions compliance.
If you wish de-CAT pipes can be used however these are strictly for motorsport use only.
The Stage 3 Power upgrade includes:
: SR Fabrications 300 cell sports cats (Motosport use only de-cat downpipes available)
: SR Fabrications performance X section in either stainless or titanium
: SR Fabrications performance back box section in either stainless or titanium
: SR 7% upper supercharger pulley
: SR/ Pipercross high flow panel filter
: Reduced fuel consumption (especially on partial throttle conditions)
: Increase in both power and torque across the whole rev range
: Revised ignition control, variable valve timing and fuel maps
Stage 4 / 445BHP+
– Upgrading to a larger core chargecooler and main radiator keeps rising intake temperatures from hot days and heat soak in check, with a 40% increase in flow and capacity a more sustained power output when running the car for track days and performance driving is then achieved for stable BHP.
The Stage 4 Power upgrade includes:
: SR 40% increase performance radiator
: SR 40% increase performance chargecooler
: SR Fabrications 300 cell sports cats (Motosport use only de-cat downpipes available)
: SR Fabrications performance X section in either stainless or titanium
: SR Fabrications performance back box section in either stainless or titanium
: SR 7% upper supercharger pulley
: SR/ Pipercross high flow panel filter
: Reduced fuel consumption (especially on partial throttle conditions)
: Increase in both power and torque across the whole rev range
: Revised ignition control, variable valve timing and fuel maps
Stage 1 / 330BHP
– Our Stage 1 package incorporates a recalibration of the engine management system along with a high flow air filter to allow for greater intake efficiency. This recalibration releases significantly more power and transforms the way the engine performs, without pushing the limits of JLR’s original engine parameters.
The Stage 1 Power upgrade includes:
: SR/ Pipercross high flow panel filter
: Reduced fuel consumption (especially on partial throttle conditions)
: Increase in both power and torque across the whole rev range
: Revised ignition control, variable valve timing and fuel maps
Stage 2 / 330BHP
– Our Stage 2 upgrade features a SR fabrications performance X section in either Stainless steel or titanium, this section replaces the heavy and poor flow shape after the CATS to further improve the engines breathing. The stage 2 upgrade is our most popular upgrade after the initial high flow air filters, and SR custom mapping.
The Stage 2 Power upgrade includes:
: SR Fabrications performance X section in either stainless or titanium
: SR/ Pipercross high flow panel filter
: Reduced fuel consumption (especially on partial throttle conditions)
: Increase in both power and torque across the whole rev range
: Revised ignition control, variable valve timing and fuel maps
Stage 3 / 350BHP
– Stage 3 Removes the restriction from OEM Catalytic Convertors from 900 cell count down to 300, this allows us a bring in power a little earlier and create a little more at the top end, adding sports cats in the stage 3 package gives a noticeable increase in performance and noise. 300 cell sports cats retain UK MOT emissions compliance.
