Fuel
The box will only run properly using 99RON fuel especially on any setting after 4. On setting 4 I worked out that I had saved roughly 10% in fuel, setting 5 is about 7%, setting 6 5% & 7 about the same as without. Push it hard in any of these though and your on a minus for sure.

I'm not 100% sure how the S5 measures consumption, but it's often calculated by the ECU according to the injector timing and fuel pressures. Tuning boxes fool the ECU into thinking the pressure is lower than it actually is, so there's more fuel going into the engine than the ECU realises.

Now having run the TDI tuning box over the Easter weekend, here's what I have found......
Everyone drives different, therefore I can only give you my personal opinion and findings regarding any fuel savings. Short of spending a fortune on fuel and racking up the miles for each setting, I have worked out a set route driving in the same manner and running on 99RON fuel on each setting.
Cost
Expensive at £649.00, but moderate driving on the default setting 4, I recon it should pay for itself in time. If you want a removable performance upgrade that does the job it is worth every penny. The S5 is a fast car, but can go a LOT faster and sound a LOT better for £649.00.

Performance.
The box certainly makes a noticeable difference to acceleration on setting 4 (default 399bhp) with a enhanced exhaust note. Up the settings and there is a notable difference to sound and performance. Setting 6 is best IMHO with a 0-62 IRO 4.0 seconds (rough timing), with smooth and very strong acceleration and great sound with some pops and bangs included! Had a race on setting 6 with a 2017 RS3 (20mph rolling start) on an empty stretch of dual carriageway and he could not overtake, even fading back in the distance a little at about 100mph. Setting 7 is a bit too twitchy for my liking so best left on no 6. I have to say that you are getting near RS performance in mode 6, and it is an absolute blast believe me....you'll love it!!
Things to Note
Only use 99RON fuel as mentioned otherwise it will not run correctly.
When plugging in harness make sure plug labels face the same way (PM me for photos).
Engine diagram of RPM plug is not very clear, so PM me for better photo.
Conclusion
Wow....get one.
Insurance
Stays the same for me anyway,but best check first before you buy one.
I'm in no doubt that someone will pull this to pieces with all sorts of 'expert' opinion etc etc.........well I don't give a sh*t to be honest, just get one and find out for yourself to see what I'm talking about.
Just to add also, unplugged it after doing about 200 miles and checked the ECU with VCDS. Nothing, no trace at all, and no errors logged.

Small part of me was hoping you would not be all that impressed thus saving me 649 quid. On the flip side it sounds like the performance is a noticeable step up!

Fuel levels were always checked with a measured amount of fuel put in for a known journey that returned less mpg on standard. Not 100 % accurate but a good indication. 'Brim to brim' x 7 was out of the question.I'm not 100% sure how the S5 measures consumption, but it's often calculated by the ECU according to the injector timing and fuel pressures.

I think it would be a great idea to have your car as the demo for the tdi chip so that we can all try your car out before we buy one
Is the sound louder on all drive select settings or just dynamic or only when you put your foot down and is it that noticeable in a good way?
When asking the insurance company what do you say it is and what questions do they ask? I've only had one car in the past that I've told the insurance company as it had a remap, exhaust and racing cats but others that had just the exhaust done I've not bothered.

Great review, i'll defn get some add on box when my car eventually arrives but might wait and see what boxes are available then.
For anyone that has a DTUK box for Golf R, it cannot be reprogrammed for S5 according to Adam @DTUK which is PITA.

Do the tunning boxes start to work less and less over time or is that just hogwash?simonwhite2000 said:

Happy to give anyone a go if you are around Milton Keynes. The exhaust note is louder when accelerating with some 'pop's & bangs' in mode 6 & 7 and when in dynamic or auto mode and sounds great. Otherwise it's much the same but with a 'throatier' tone to it. I informed the insurance company that I had installed a plug in tuning device, and gave them the item details via email. They just noted this on the policy after speaking to the underwriters.I think it would be a great idea to have your car as the demo for the tdi chip so that we can all try your car out before we buy one

Smoked rear lights, not usually a thing i like, but i like them here.

I am glad you mentioned it causes some pops and bangs in mode 6 and 7 as otherwise infeel the only other way to achiece this would have been new exhaust!Great write up!
