JTK Remapping is an ECU remapping and vehicle tuning workshop in Dungarvan, Co. Waterford. We get more power, torque and fuel economy from cars, vans and 4x4s, with every map written in-house for the vehicle in front of us.

Our background is motorsport engineering, and every remap is custom-written in-house by a qualified motorsport engineer. That means a map written for your engine and the way you drive, measured on our own all-wheel-drive dyno before and after, so you see the difference on paper as well as on the road.
We're the official APR dealer for the Republic of Ireland and authorised dealers for Milltek and Scorpion exhausts, and we remap a wide range of vehicles, including:

A Stage 1 remap is for a vehicle in its standard factory form. We recalibrate the engine control unit (ECU) software to get more from the engine, with no hardware changes.
It's the most cost-effective way to a noticeable gain in performance, and the car keeps all its original parts.
Performance RemappingA Stage 2 remap builds on Stage 1 with hardware upgrades alongside the ECU recalibration, typically a performance air intake, upgraded exhaust parts and a better intercooler.
With those, the engine breathes more freely, and the power gains go up a clear step.
Performance RemappingA Stage 3 remap is for maximum performance. It needs major hardware upgrades, such as a high-performance turbocharger, an upgraded fuel system and strengthened engine internals.
The ECU is then recalibrated around those parts, for the biggest power and torque figures of all.
Performance RemappingRace and rally car preparation: our motorsport engineering background goes into engine performance, handling and safety, built to the standard your class demands.
We also fit APR tuning products, including turbocharger systems, intake filters, brake lines, throttle boosters and suspension control unit upgrades.

Have to say I had an incredible experience with JTK.. emailed them and got all their suggestions for what I should do with my Golf GTI as I have no idea John was very helpful and booked me in and everything went smoothly on the day and the job took the time they said it would. Couldn’t recommend them enough and the receptionist lady was very helpful and friendly sorry forgot her name.

So I got a hybrid turbo from muchboost installed in my Mercedes c220 and was advised to get a custom remap on a dyno so I contacted John got it booked in and he also offered hydro clean as an option and It was worth every penny I couldn’t believe the difference it made plenty of power and ticking over like a dream thanks again
