19th Jun 14 Hello Niclas, Yes I do have a DTUK module on my S5. I have had it for about 1 year and covered around 15,000 miles. The box transformed the car, I loved the S5 however it didn’t give the performance buzz that I was expecting from a 3.0 supercharged engine. The box was simple to fit, great quality and has performed effortlessly with no problems whatsoever. There are four power maps to choose from offering different power delivery, then three additional tweaks for each map. So 12 maps in total on the box. I have chosen a map that peaks the power quite rapidly at about 2,000rpm. It has made the car much faster, I did a series of 0-60 runs and averaged around 4.3 seconds which is 1 second faster than the cabriolet as standard. I had it tested on a dyno about 6 months ago and it reached 424.6bhp as the highest figure of three runs, the lowest was still 421bhp. I run my car on map 4+3 so the highest setting on map 4. The only additional engine work is a Pipercross air filter, modified airbox and throttle body inlet hose. These won’t have added much of the HP improvement. I’d recommend this box to any S5 owner, five minutes to fit the box and just a two minutes after that once you know what your doing. This is my third DTUK box and although the others were great, this is by far the best. Rob Sent from my iPhone
