DTUK - Performance Specialists

I bought an FSR+ tuning box from DTUK in early 2023. It's actually my third box from them, had two other boxes for two previous (turbo diesel) cars and have always found them reliable and powerful. This time, I've got a VW Golf GTE (a petrol/electric hybrid) and initially it caused a few frustrations as the GTE's powertrain is a bit "quirky" in how it delivers its (more than adequate) performance. However, Andrew from DTUK couldn't have been more supportive and helpful, spending many hours on the phone with me to sort these minor issues out, until we finally nailed it. Great company with super after-sales support. Definitely recommended.

A bit of a mixed review to be fair, in brief performance great.but transferability of tuning box, disappointing. I bought a TDIUK tuning box brand new from them in 2017 to use on my 65 plate Skoda Octavia VRS 2.0TDI. A definite improvement in drivability of the car in terms of power and torque, ok there were a few niggles and fault codes but otherwise all good. At the time of buying it in 2017 it was then latest and greatest TDI box, and it was promoted to me as being transferable to future vehicles. During late 2019 I bought a Skoda Karoq 2.0 TDI and hence not something radically different from the prior Skoda in terms of the engine plant..and sadly it wasnt transferable or even able to be upgraded to be transferred. This is only a 2.5 year window, using the then current TDI box and potentially transferred to a vehicle by the same manufacturer and on pretty much the same diesel engine plant. Reasons X,Y and Z given by TDIUK at the time, ok fair enough..but I was left with a 350+ tuning box in hand which was no further use to me at all! So in reflection would I buy another one, yes I probably will..but to be clear it wouldnt be on the basis of re-using the tuning box on future vehicles. Sadly there are always going to have subtle changes and future compatibility with the next vehicle, even if its the same car maker. Plus then potentially TDIUKs supply chain changes also kind of negates any reusability value.

Terrible service and customer support. They wouldnt answer the simplest question I had which was which box do you sell which is best for power and performance. Instead was incredibly rude and sarcastic. Dont buy off them save yourself from future problems which they will not help you with.

I ordered the CRD+ Tuning box for my US Spec 2015. BMW 535d X-Drive M-Sport. Andrew's communication before buying was axcellent and he sent me detailed instructions on installation which was a breeze apart from some of the original sensors were difficult to take apart. After I turned the car on, it went into limp mode even on the lowest settings. Even when I disconnected it, it stayed in limp mode. I contacted Andrew who was very helpful in running some possible fixes and when going through those, I discovered that on my car I had to unhook the O2 sensor and hadn't plugged it back in! As soon as I did, the car ran great. I love the performance gains and fuel economy has improved too when I can stop the urge to floor it (very difficult!). Andrew's customer service skills are excellent. And with the time difference, he went so far as to work during the evening with me. I couldn't be happier! Thanks Andrew!

Waste of time and money their boxes, if you will have chance invest in remap as their boxes generate faults and car going into limp mode. They already replaced one box for me but fault come on again after one year , now they just ignore me or telling me that its not box fault, but that really strange as happened before and they replaced and been ok for year and when Im running car without box its no faults, obviously warranty is useless, try before return for refund no chance, now just ignoring me and telling me that they tune lots of cars without issues, so must be my car. A yeah al8. Be careful with this company
