EXCELLENT Based on 106 reviews Nigel lingo After my mk7 transit van went in to serious limp mode. I gave it to garage to sort out. Spent £700 on dpf clean , parts and labour. Two days later back in limp mode saying dpf restricted and egr stuck . So i found James at NXT performance and spoke to him. He reasured me he could sort the problem and swiftly booked me in. I dropped the van of in the morning to have my DPF and EGR sorted. He also done a complete diagnostic on the van before sorting the issues. He kept me informed the whole day and i could collect it that evening. Sure enough the van was sorted no more engine lights and engine malfunction lights or limp mode. Realy nice honest professional bloke!. Van drives lovely! I should of taken it to him straight away. But lesson learned. Thank you so much!!!!! Will be back for the limiter to be taken of at some point. Lee Phillips Just had my Audi A4 TDI remapped stage 1 and absolutely over the moon with the results after being let down somewhere else NXT Performance fitted me in at short notice thanks for that. Just drove home from Worthing to Basingstoke and my fuel gauge hardly moved from full tank and performance wise very noticeable with the acceleration and torque made me smile and very happy definitely would recommend thanks NXT Performance ⭐⭐⭐⭐⭐ Gary Heatley Just had stage 2 on my 330d very happy with the work done had good chat asked a few questions and got all the answers I needed also had stage 3 gearbox map James yet again above and beyond I can feel the car and gearbox working together gear changes really smooth and all the power when I need it also have to say James makes you feel your part ov a family rather than just taking the money and running I have already told a few people to get in touch this company definitely knows his stuff cheers James I’ll be back with another car soon Neil Green Had an issue with the dreaded ad-blue, James was round quickly and sorted the problematic system so now I’ve no more issues to worry about.

Tony Portsmouth Excellent service by NXT had DPF filter sorted and remap stage 1 done van runs a treat with no warning lights James is very helpful and answers all your questions Would definitely use again. Glenn Bennett Came down and mapped my Astra. ECU had to be removed as couldn't be flashed over OBD - no problem. Removed ECU, flashed and had it all back together in an hour. Car runs sweet, really happy with performance increase - no problems at all. Awesome. Emad Siddiq I recently had the pleasure of using NXT Performance to work on my Toyota Proace Verso, and I couldn’t be more impressed! What really stood out was their mobile service, James came straight to my home, which was incredibly convenient. James was professional, friendly, and clearly very knowledgeable. They explained everything in detail before starting the work and kept me informed throughout the process. The quality of the work was outstanding, and my Proace Verso is running better than ever! His attention to detail and dedication to customer satisfaction is unmatched. It’s rare to find a service that combines expertise with such convenience and top-notch customer care. I highly recommend NXT Performance to anyone looking for exceptional mobile service and expert workmanship. I’ll definitely be using them again in the future. Thank you, NXT Performance, for making the whole experience so seamless! ⭐️⭐️⭐️⭐️⭐️ Easiest 5 stars I’ve given. Very well deserved. Nils Lejins James did an excellent job on my BMW 1 series, really knowledgeable and very friendly . Toby Tudor-Williams James from NXT went above and beyond to help us resolve our car issues.

Car remapping is a process of electronically tuning a car’s engine to optimize its performance. It involves reprogramming the vehicles’ Engine Control Unit (ECU) to modify the timing and other parameters that control how the engine runs. This can result in improved torque, power, acceleration, and fuel economy.
Car remapping is a relatively simple process that is usually done with a specialized computer. First, the car is connected to the computer via diagnostic port. Then, the technician will upload the car’s existing ECU map and modify it according to their specifications. Once the desired modifications have been made, the new parameters are saved onto the car’s ECU, replacing its old map.
Car remapping offers many potential benefits for the car owner. It can improve a vehicle’s fuel economy by up to 15%, and its power by up to 40%. Remapping also allows for greater control over the car’s performance, as it enables users to fine-tune the engine for particular conditions or driving styles. As well as providing improved power and performance, remapping can also reduce emissions and enhance safety features such as ABS and traction control systems.
After a car has been remapped, it is important to keep some key points in mind. First of all, a car should not be driven beyond its rated parameters. Over-revving the engine can put excessive strain on components and affect the lifespan of the vehicle. It is also important to ensure that the correct oil grade is used for the engine, as this can have an effect on fuel consumption and power output. Finally, regular checks should be carried out to make sure that all sensors are functioning correctly and any faults are investigated.
The amount of time it takes to get a car remapped will depend on a few factors, including the type and age of the vehicle, the complexity of the remapping process and how many performance upgrades are being made. Generally speaking, most cars can be remapped within a few hours, however some more complex upgrades may take up to a day or two.
