EXCELLENT Based on 201 reviews Posted on Paul CMay 28, 2026Trustindex verifies that the original source of the review is Google. James was brilliant sorted the van and runs perfect now cheers for that top fellow good price as well would use again thanksPosted on steve kinderMay 26, 2026Trustindex verifies that the original source of the review is Google. Privileged to be number 200 five star review. Blown away by the results. James has been helpful, knowledgeable, open, honest, patient and charming throughout the process. I highly recommend these people. It makes a very pleasant change to have a faultless service and transactional experience.Posted on Jacob AtkinsMay 12, 2026Trustindex verifies that the original source of the review is Google. Shout out to James at NXT, who remapped my C43 AMG (W205), to a Stage 1, the difference for the price is ridiculous! The car feels awake. Very noticeable gains in power and torque, far sharper gearbox response, improved throttle response, and it now pulls hard throughout the entire rev range. It feels quicker, smoother, and far more eager to go without losing any drivability. James was punctual, professional, clearly knows his stuff, and took the time to answer questions properly. If you’re considering a Stage 1 remap, and you've received a quote, get it done. For the money, the improvement is hard to beat!Posted on Nick KnightMay 9, 2026Trustindex verifies that the original source of the review is Google. James provides a very professional 'remap' service. He was extremely informative about the process. The car has significantly increased both its BHP and torque and has become much more 'throttle responsive with less turbo lag. I am very pleased with the outcome. Thank you James.Posted on David KingMay 3, 2026Trustindex verifies that the original source of the review is Google. The guys did a fantastic job on my Ford Ranger. Low miles and persistent DPF warning lights which eventually led me to spending 2 hours on the side of a busy motorway. Tried cleaning and replacing components but nothing seemed to help. Worried about future costs, I took my truck to NXT and the guys worked their magic. 300 mile journey this week and not a warning light in sight. Thank you NXT!Posted on AdamMay 3, 2026Trustindex verifies that the original source of the review is Google. Brilliant service…. Very informative.. Remap on my 5 series has made it fantastic and fun to drive ! 💪Posted on Adam BarnesMay 2, 2026Trustindex verifies that the original source of the review is Google. I had an exceptional experience with NXT Performance, and in particular James, who has completely transformed my van. The improvement is immediately noticeable. The vehicle now drives smoother, feels more responsive, and overall has a level of refinement that genuinely makes it feel like a brand-new machine. The difference in performance and drivability has exceeded all expectations. Considering the extent and complexity of the work carried out, everything was completed efficiently and within a very reasonable timeframe. It’s clear that NXT Performance operates to a very high standard. There was no sense of doubt or anything being rushed, just careful, precise workmanship and real attention to detail throughout. The end result speaks for itself. James is an absolute credit to the business. He’s incredibly approachable, friendly, genuine and easy to speak with, while also being highly knowledgeable and professional. He took the time to explain everything clearly in a way that actually made sense, offered honest and practical advice, and was always willing to help with any questions. What really stood out was how he consistently went above and beyond. Nothing ever felt like too much trouble, and he genuinely cared about making sure everything was right. Equally, a lot of credit has to go to the mechanic involved in carrying out the work. The quality of the workmanship is evident in how the van now performs. Everything feels solid, refined, and properly put together. It’s clear there’s a high level of skill, experience, and pride behind the scenes also, which plays an equally significant part in achieving such an outstanding result. What really sets James and NXT Performance apart is the level of care they put into both the work and the customer experience. It's obvious there’s a genuine passion there, along with a commitment to doing things properly and delivering the best possible outcome. It’s not just about getting the job done, it’s about getting it done to the highest standard. It’s rare to come across a service where everything from communication, to quality of work, to the final result exceeds expectations, but that’s exactly what I experienced here. I genuinely can’t praise James, the team, or NXT Performance enough. If you’re considering this type of work, don’t hesitate or look elsewhere. James and the team are absolutely the people to go to! Thanks again James & NXT performance for restoring the faith in my vehicle!Posted on revilowMay 2, 2026Trustindex verifies that the original source of the review is Google. I can’t fault NXT. These guys really know what they’re doing and care about the service they offer. James remapped my 2016 E350 Mercedes a few months ago and has transformed the way it responds to throttle inputs. Massive torque gains mean it can now scare some pretty serious machinery which is good fun too! He was very informative throughout the process and even re-installed the map for free when a dealer wiped it during a gearbox software update. Great service.Posted on james lloydApril 25, 2026Trustindex verifies that the original source of the review is Google. Great service, came out to my cars location which was with my partner round her friends house. NXT PERFORMANCE can literally remap your from your doorstep. Great service, speedy and no messing about.Posted on Dave ThompsonApril 24, 2026Trustindex verifies that the original source of the review is Google. Prompt and punctual callout. Friendly, expert service. They were helpful and obviously knew what they were doing. I'd definitely use them again, and recommend them to others.Verified by TrustindexTrustindex verified badge is the Universal Symbol of Trust.
