Opel 1.9 Vectra CDTi 150Hp
Recently installed DTK on a Vectra 1.9 CDTi 150. Have driven about  2000 km since and have to say that I am very pleased with the box. Installation was super easy. The contact fit perfectly and the DTK box was put in the battery case. Noticed immediately that there was more response punch with the same motor characteristics as before. Have ”fine tuned” a little afterwards and the pot meter screw is about 5-6 turns out (more diesel) compared to originally. This has primarily made the motor brisker in the upper range of the efficiency scale. It seems that the DTK box was set up a bit “cautious” originally. Have not noticed any jerking or any soot from the exhaust. Diesel consumption has actually gone down somewhat.

Opel 1.9 Signum CDTi 120Hp
Have now tried out how it worked and so far it has been top notch. Can tell you that it was a completely different car to drive. Whereas I often had to gear down from 6th to 5th, I no longer had to change gears. On a trip up to or back between Kr-sund – Tr.heim, I consumed an average of 0.52 l per 10 km. I could hardly wait to read the consumption when I came up on Sunday. Believe it or not, the fuel consumption was 0.47 l per 10 km. Incredible… I didn’t drive slowly to conserve fuel, but drove just as I normally drive.

Bought the box this summer. Was on my way to the mountains, the same day I picked it up at the post office. With great scepticism and a screwdriver, I installed the box. I felt the motor functioned a bit differently in the beginning, but I wasn’t convinced…Thought about the guarantee you give whereby it could be returned if one is not satisfied….that’s as far as I went….the box will not be returned for anything in the world. Lots of power from 0- and up to 170 km/h. The car consumes much less diesel. We (three men) drove on the Autobahn at a speed of over 200km/h and long stretches at over 170km/h cruising speed. Normally this would mean draining the diesel. But when I parked the car on Friday, the average fuel consumption averaged 5.2 l per 100 km and I have never been able to get that with this car.

Thanks for your quick shipment of the ”tuning box” I got today. Have installed it on my Suzuki XL7, and mounting it was relatively easy (it was a little tight filing away nicks on the contact) have of course test driven all evening and am very pleased with the box. Can be highly recommended at a reasonable price…

Ordered the DTK box for my X-trail 2002-model. Quick delivery. The car has a powerful motor originally. But now it has much better pick-up at low rpm. This was worth the money. Am expecting lower fuel consumption. Incredibly easy to install on this car, 1 min.

I have tried the dtk box on my car, I have got much more torque. It accelerates much faster than before, has much more power in the motor, it was absolutely worth the money, am super satisfied.

In the mountains I installed the miracle DTS box. It was an unbelievably positive experience!!! First of all the installation was incredibly easy!! (Was that everything???) The only problem was that the plastic cover had sort of special screws, but I had a cheap bit-set I had bought at Claes Ohlsson and it had the right bit. It felt like the car had got an extra turbo! It accelerated better and extended acceleration significantly farther than before. And as if that were not enough: On the way from Oslo to Oppdal, the average fuel consumption was 0.72 l per 10 km. On the way south, with the miracle box on and exactly the same car weight and (fast) speed the consumption was 0.6 l per 10 km in a significantly faster car!!

There was a contact we examined and tried to get off, but it was attached so hard and didn’t look the same as the other ones. So we gave up. However, I just went out and tried to get it off again, which I finally managed to do, and then it slipped right on. Haven’t test driven yet, but now I reckon it will work. Thank you for fantastic and outstanding service!

Hi and thanks for good service. 10-pole contact is installed and is working well. More pep and 0.5 dl less fuel consumption. 8-pole contact sent back yesterday.

Have now installed the box and tested the car. Am very satisfied with the result!! Was a little sceptical towards it, but it works very well!!! The car finally has some real torque!!

The tuning box works wonderfully now I am looking forward to trying it out on a longer trip.

Efficiency is markedly higher, but I prefer to gear up at about 42000 rpm instead of 4500 rpm that this chip permits. Nevertheless much faster acceleration, as well as the same power with a fully loaded car as with an empty car originally!

To put it simply, there are various hills in my local area that will never be the same after this! Based on what I tested out this weekend, it looks like this is an efficient little rascal!

This evening I was out testing the car and it seems that it has got new power! I clocked the time from 0 to 100 (on the speedometer – which is maybe not totally precise, but nonetheless…) and I clocked it at 9 seconds – not bad! There is no more exhaust fumes than before – on the contrary. I read in the instructions that I can get even more power out of the box – is that a smart idea, or should I leave the car the way it is?

Bought a new chip at http://www.biltuning.no/ the result was a peppy car + fuel consumption on long drives now averages 0.42 l and during the last 500 km, consumption was 0.48 l per 10 km. this is about 1 to 2 dl. less than before per 10 km, so I am very satisfied with this, installation was completed in 10 min.

Yes! This went really well! Installation went incredibly well and I am NOT a car expert. The first thing I noticed is an unbelievable improvement at low rpm. Am a salesman and drive a lot and the number of gear changes declined significantly. I have an automatic gearbox and was anxious about how it would cope with the tuning box, but I am absolutely satisfied so far. Haven’t yet had the time to measure fuel consumption over time, but so far I have noticed neither an increase nor decrease. Don’t understand how this actually works, but the box is brilliant for me nonethelessJ

Think you are right regarding a lot of diesel. Everything works ok both at full and medium throttle, there are no exhaust fumes at all. Now I drive a few days the way it is, and when the light comes on I adjust the amount of diesel intake down as the manufacturer suggested. In addition the car accelerates tremendously from 0-70km.

It took only 10 min, I spent most time attaching wires with cable clamps and making room for the DTK cable inside the fuse box on the right side. But there was ample space for it there and it is located safe and dry. Have been out test-driving now and I haven’t noticed any more exhaust fumes than normal, will I see that when it is idling, too?  Or is it when you down-gear? Think it works really well, have got more pickup and the automatic gearbox seems to like it, too. I am very pleased so far, and the fact that it wasn’t hard to mount/detach I think is an advantage. It allows you to take it out when you take the car in for service or when you want to sell it. So thanks for your help so far and I hope there will be no problems in the future.
Regards from a satisfied customer.

Easily burn rubber now with the mounted DTK, Can the automatic gearbox really withstand this? 3/4 throttle and the rear wheels 245 /40/18 lose grip. Thanking you for your reply
