MERCEDES-BENZ E-KLASSE (W211, S211) E 420 CDI 314 HP

“ Very good communication with the customer. All inquiries will be answered quickly with a solution. That's service! ”

“ Good support for self-installation, system functions, better performance with low fuel consumption. ”

“ I was at the company and the installation was without problems. A test drive then showed the subjective performance boost. After a year with the box my fuel consumption has not increased (fuelbook logging). So all is well! ”

“ Product is top! It delivers what it promises! ”

“ Was very satisfied with the fast delivery, and I also was very well advised by a technician over the phone and could therefore install my components without problems in my vehicle. ”

“ My car is now great. I'm very satisfied with the tuning. The installation was easy. The delivery was the next day with me. I had a technical issue that could be resolved over the phone. I'm very satisfied with the product and the support ”

“ I now know my car barely. I never thought that it works so well. Will naturally recommend it. ”

“ I use DTE Systems products already over 7 years. Always have always received exhaustive information, regardless of which contact I have chosen, phone or mail. The products PedalBox and Chiptuning in my opinion are the best you can get on the market, the products have never let me down and do what they promise. ”

“ Expert advice, fast shipping and the quality of products (chip and pedalbox) I can judge well as a former car mechanic. I use both and the difference in acceleration dynamics and performance improvement is tremendous. The chiptuning and the pedal box harmonize together perfectly. I'll also need 1 - 1,5l less diesel. My vehicle has almost a motorsport feeling and I can not imagine driving without them. Great company! ”

“ I deliberately chose a tuning box of DTE Systems, because the increase in performance remains in a realistic magnitude and a certificate of conformity was included. The installation was relatively easy. Just as the acceptance by the TÜV. Was actually quite happy with my performance. However I lacked in some situations more pressure out from below. After installation of the box, the torque increase already in the lower speed range is appreciable. The fuel savings are in my case about 0.5l per 100km. The default setting of the box has not been altered by me. After 2000 km so far there were no problems. The shipment of DTE Systems is very fast. The service is very good, although I hardly had to use it. ”
