Custom Computer Tuning for Volkswagen & Audi

Increase performance on your car by custom tuning the onboard computer.

  • Fixes factory flaws, such as the hot-start issue found in ’98-99 MK4 Golf/Jetta and New Beetle TDIs. Most ’98-99 TDIs require several cranks to start the engine if the coolant temp is warm. All our tunes fix this issue.
  • Elevated idle for cold climate to improve engine warm up time
  • Dynamic EGR control: EGR-on while cold to speed up the engine warm-up period (good for fuel economy, in-cabin heat, and reducing cold cylinder wear & tear), EGR-off while warmed up to minimize or virtually eliminate soot build-up in the intake.
  • EGR delete (off-road only) (tuning boxes will not suppress a check-engine light).
  • DPF delete in 2009 and newer TDIs (off-road only) (tuning boxes will not suppress a check-engine light).
  • Exhaust/hi-flow catalytic converter upgrade in gasoline/diesel engines (tuning boxes may not suppress a check-engine light).
  • Air Intake Flap delete (common for intake manifold upgrades in some vehicles) (tuning boxes will not suppress a check-engine light).
  • MAF sensor delete (tuning boxes will not suppress a check-engine light).
  • MAP-sensor upgrade. Many turbo upgrades need a MAP upgrade to allow full boost with factory overboost protection retained. Some tuning boxes will circumvent the factory overboost protection, and you need a boost gauge to see the actual boost.
  • 100% VW dealer and VCDS (VAG-COM) compatibility. Tuning boxes skew OBD2 data; the engine computer sees less accurate injection and boost data because the boxes alter them outside of the ECU. They may also skew the fuel economy meter in instrument clusters and aftermarket OBD2 fuel economy meters.

    We have a 91 Westfalia with a 96/97 TDI engine that decided to stop working (in a rather spectacular fashion with LOTS of smoke and noise) on our cross country trip on the I-90 near Sioux Falls. Alex
    was able to figure out what was broken (luckily only the turbocharger) and get us back on the road within a couple of days. He impressed me with his knowledge and attention to detail. I would highly
    recommend him.

    Loved the service and Alex is always so friendly, honest and helpful. He does a great job. Best prices and he actually tries to make sure he get's the best prices around for repairs and never
    overcharges. Honestly best mechanic I have found to date, and would recommend him to any girl scared to walk in a repair shop alone! He is honest and takes care of you like his family - Thanks Alex!

    I traveled 800 miles with my Audi A3 TDI to get to VDUB, based on all hat I had read on the web.
    There they took good care of me and even better care of the car.
    Everything was inspected , maintained and if necessary repaired.
    And the result is a car that is good for many more miles.
    The web was right!
    Was it worth the drive?
    Absolutely, there they know what to do and to do it with the perfection Germans are known for but that can also be found in Sioux Falls.
    I can every VW or Audi TDI driver within 800 miles advice to go to this place if you're serious about maintenance or repair.

    Alex knows his stuff. If he does have a question he will do the research and get back to you promptly. Always pleasant, you get to ask the mechanic your questions directly. Alex will lay out your
    options to match your budget. He is a "straight shooter". If you want to have some fun ask him what he would do next to your car. He makes good suggestions.

    My VW Jetta was in need of an emergency repair and Alex was most helpful! In my eyes, he just has passion for what he does. He explained everything clearly and did a great job fixing my car, along
    with some other modifications. If I lived in Sioux Falls, I'd take my VW there every time it needed to be repaired, or even just for an opinion. I've had many mechanics work on my car and I am always
    worried that they may not have the knowledge of how to work on German cars, but not Alex--he's got it!

  • Jeremiah Lindgren (Monday, June 23 14 03:24 pm EDT)

    I contacted Alex to do a Malone Tune on my brand new 2014 Passat Diesel. Alex responded to all my questions very quickly. The day I had the tune done, he was very courteous and everything was done
    very quickly. He is a great guy and very helpful. I will take my car back to him when I need more work done to it in this fashion, even though I live 8 hours away!

  • Lisa W (Sunday, March 30 14 11:31 am EDT)

    Alex is a wonderful mechanic. Trustworthy, very knowledgeable and enthusiastic. He is my first choice in all repairs on my Jetta!

  • DeLora (Friday, February 21 14 10:40 am EST)

    We took our Audi to VDUB to get a second opinion after going to the local Audi dealership. We are so glad we did! Alex did a great job diagnosing the problem at a much lower cost to us than the
    dealership. Alex also listened to our concerns and did a great job explaining the problem.

  • Kathy (Saturday, August 31 13 01:57 am EDT)

    VDUB is the BEST of the BEST. I know no one will ever match their expertise and quality of work. You won't be sorry. Thanks VDUB, I'm so glad I found you.....
