We at JC Remaps offer many services which include; custom re-mapping stages 1 and 2 mobile in 100% of England and Wales, if stage 3 is needed we have dyno in Shrewsbury. Carbon engine cleaning is available when booked on its own in Shropshire, Staffordshire, Cheshire Powys, North Wales, Birmingham and other areas surrounding Shropshire, DPF cleaning is only available in Shrewsbury/Telford/Oswestry. Mileage correction in Shropshire, DSG gearbox tuning is mobile in England and Wales. Our smoke boost leak detection is mobile in Shropshire. We refuse to go out to vehicle's which are already mapped this is due to other tuners locking the ECU, and I'm some cases them locks can cause major damage.


All our remaps come with FREE: 



(This disables the functions and can save costly repair bills this is also done to add performance gains)


(This is generally for vans with the 70MPH restrictions)


(This is would be for vehicles with decat and will stop the engine management light coming on and will stop the car from over fuelling)


(POPS AND HARDCUT THE CAR MUST BE DECATTED IF PETROL COMPELTELY STRAIGHT THROUGH IF DIESEL IF NOT THIS WILL CAUSE MAJOR DAMAGE). These modifications can be carried out at our Shrewsbury garage's as we need a ramp, the process is 2-4 hours labour so we offer a drop off service to the local town centre. 

We can also offer; 


(DPF MUST BE REMOVED FIRST OR WILL CAUSE MAJOR DAMAGE. You can not just delete the DPF it must be removed if not the turbo will blow up and cause major oil leaks and potentially destroy the engine) We can offer this removal service in Shrewsbury.


(This would be for vehicles fitted with this system and have removed the DPF so no longer need it. There are cases where the ad-blue can fail and will be costly to repair so again in this case it can be a option to delete it.


(The most common code we see is the p0401 relating t the EGR not working due to blanking or to much carbon removing this will then remove the engine management light, other codes can be removed that's relate to other problems.


STAGE 1 = No mods are required for this, we will write the map from your stock map off the vehicle's ECU according to dyno proven results. Safety specifications on parts and then adjust according to the mileage.

STAGE 2 = This will adapt from stage 1 and will be with modifications which are needed such as induction kits, panel filters, exhaust mods mainly decat and DPF removal and then an upgraded intercooler. (Please contact us if DPF removal is required along with decat.)

STAGE 3 = This again adapts from stage 2 but will require more mods, the more you push the vehicle the less lifespan is expected of it. Stage 3 modifications will be things such as larger/hybrid turbo's, bigger fuel pump, bigger injectors, water meth kits, nos kits and forging of the internals making it more like a track day performance vehicle.


-OBD Jobs will be the most easiest method of tuning a vehicle, if the tuning tools on the market have not managed to unlock the OBD yet then its a case of using BENCH, again if that's not yet unlocked its a k-tag BOOT. 

OBD JOBS Are the easiest method to tune and take up to 90mins with no need to remove ECU.


In most cases this is because nobody in the industry has a way to access via the OBD, Or in other cases its when poor tuners lock the ECU When they have already tuned the vehicle.

DSG & BMW Gearbox Tuning.

DSG/BMW Gearbox tuning is custom - there are light modifications for the tuning that can be made to improve shift speed, responsiveness and smoothness of the gearbox and power delivery. Significant gains in torque delivery can be achieved; track day and sports enthusiast drivers will simply love it. Our DSG & BMW Gearbox remapping offers 70% improvement in shift speed and significant ¼ mile and 0-60 improvement. At JC Remaps, our DSG & BMW Gearbox remaps is measurable, demonstrable, and very noticeable - you will really enjoy these changes and that's a money back promise of 7 days. 



Are you worried you have a leak? Have you got turbo  boost issues or EVAP DTC? Can you hear a louder whistle noise than normal? Leaks as small as a EGR gasket missing or sowing needle size can cause issues and develop into bigger issues, these are next to impossible to locate. The only way is smoking, we use a professional machine to find these leaks and can be detected in minutes making it easy to replace.



If your DPF is blocked or clogged, you will typically see an orange light on your dashboard. The light is usually an icon that represents the DPF filter itself - a piped box with dots in the middle, but this varies and depends on the manufacturer. 

DPF Removal

The fitment of a DPF (diesel particulate filter) is a legal requirement in the UK, and across many parts of the world, so removing your DPF is illegal, even if it is blocked. You can face a fine of up to £1,000 for cars and £2,500 for vans if you are caught removing your DPF filter, and it can also invalidate your car insurance policy. We of course offer DPF delete if its been removed and can arrange removal in Shropshire should you wish to come to us, we will always do our up most to make the removal discreet and will help you with the MOT.

If you are having issues with a blocked DPF, then the simple solution is cleaning or DPF regeneration, rather than running the risk of removing the filter entirely.

98% success rate for blocked DPF units.

2 Months warranty. 

Free diagnostic included.
