They did an amazing job with my Stage 1 ECU and TCU remap. I have a MK6 GTI and it honestly feels like a completely different car now, i've driven over 200 miles on it and every time i accelerate i get the feeling i had when i first bought the car.They did checks on the car before putting on the map to find and diagnose any error codes. I have an upgraded GFB diverter valve which was throwing an error and was quickly resolved as the ECU expected the stock DV.Very happy and would definitely recommend to anyone looking for car remapping in London. Also the waiting area is nice with Good wifi.Will be back for stage 2 tune and intercooler in the future. Thanks!!

Great service by the team at HT Customz.Explained entire process. Their work has transformed my 10 year old VRs! Thorough and diligent in their work! Cooking up a BBQ when I got there so food too 👏👏👏👏

Amazing service! Really great and funny guys! Would definitely recommend 10/10

Had my exhaust and remap done on my A35 AMG by HT Customz. Great service, top-quality work, and the car feels and sounds amazing now. Really happy with the results and would definitely recommend them. Thanks again!

I have had a little stressful time with my Polo GTI , but Antony and the team always put the time out for me! to fix any issues that have occurred! Everything is up and running now and she sounds like a beast! Thanks team!

Took my c43 to ht customz for cat delete, stage 1, ecu tune, with added pops and bangs tune, I told them I wanted it to be silly loud when it returned to me I had to tell them it’s too much 😂 absolute monster they even said bring it back they’ll dial down the pops and bangs free of charge for me, great company and easy to work with

One of the best places to get your car customised. I would 100% recommend these guys for customising your car. Excellent turn around time and always keeps you updated with progress. Can’t fault this company.
