Mk5 R32 Turbo. I have had the best experience top quality service I would not think about going anywhere else! From helping me install my ecu over the phone with help on wiring sensors troubleshooting I would have been totally lost not to mention the remote mapping service so I was able to fit it in around work and other things the car runs like a dream pulls hard in all gears and is music to my ears. I will not take my cars anywhere else 5* Thank you for bringing my project to life
Sam always does a quality job when it's comes to mapping my car. It has been with Sam multiple times for mapping, tweeking and problem solving and is very knowledgeable when it comes to ECU masters. The passion toward cars and mapping reflects in his work!
Something came up that required me to get a car part urgently and under a time limit and I was having trouble tracking down local businesses that could source it for me. Luckily, I came across Sameer’s contact information and reached out. He was brilliant - answered my query over the phone, got the part ordered as soon as was physically possible and kept me updated every step of the order and delivery process. He solved my issue with professionalism and expertise. Very happy with the service received.
Absolutely great services. Great communication. Always ready to help. My car is now faster, more reliable, and made way more power. Sam is the man.
Sameer was incredibly helpful all the time, always available to answer questions and provide support. Lots of knowledge Highly recommend.
Great Service and always willing to help, even if we are not busy tuning the car all the way in Namibia! 🇳🇦
