Ok so here’s my feedback coming from a stage 2 S3 and a JB4 box on my Golf R I’ve now had a DTUK box on my A35 for a week slowly working up through different settings. For me it’s not about dyno figures or graphs (although nice to have) but more about how the car drives. After my last two tuned cars the car felt a little breathless and flat from 2,000rpm , the noise and the handling was there just a slight hesitation after changing gear whilst waiting for the revs to build. With the box on this has gone and then some, the car now effortlessly catapults out of a B road corner and pulls very hard to the next gear change where it keeps on building and building. Checking the speedo reveals some silly numbers very soon. It’s much more of a matched package and now performance per £ is astonishing.
The cars remains a consummate daily driver and drives very OEM you would not know what lies beneath without pressing the happy pedal, gear changes remain smooth and well timed.
Installation was very simple half hour max taking time to route cables to 3 sensors and find a home for the box next to washer filler neck.
