MAF-Less Tune:

This means I will be using your map sensor for fueling control. So you can leave your maf unplugged, and install any Maf housing you wish.


Immobilizer delete:

This allows your vehicle to start when you replace your stock ECU with a tuned ECU. This will also allow your vehicle to start if your key’s transponder fails (This is a common issue on the MK4 platform). *NOTE: If your key fails with immobilizer delete your vehicle will still start, However, you will still have a flashing key light until you adapt another key to the cluster.


Additional Options:

Crackle Pops/Burbles Options (be sure to note your preference in the comment box. The default is set to intense):



  • INTENSE (This will cause some vehicles to make flames, if the vehicle is straight piped.)  


Two Step/Anti lag/Launch Control 

  • On average, this option is set to 4500rpms. *NOT AVAILABLE FOR AUTO TRANS MODELS*



Special requests available

  • AEB cylinder heads Only - VVT (Variable Valve Timing) Removal 

MBC (Manual Boost Controller):

This is a small device that goes between the pressure side and the wastegate , and gives you the control to set boost pressure to a desired level. BDT’s tune only allows the car to boost between 0-23psi. In the event you set the controller higher than 23psi, Boost Dynamic Tuning is not responsible for catastrophic events. 


 You can receive a $50 core refund, if I receive your old ecu by mail. Please check out our "Shipping" information here.

    Totally Different Car

    Posted by Ryan on Dec 26th 2023

    The test drive after the install, I was smiling ear to ear the whole time. Walked back into house and my wife was like “you just put that new ECU thing in your car didn’t you? There’s no other reason you’d be smiling that much”. Throttle response is great, and so much more power with the stage 2. I’m super pleased with these guys’ work. It woke the GTI up and made it a completely different car.

    Stage 2

    Posted by Matt Vaughan on Jan 29th 2023

    I really like this plug play unit. I really wish there was a specific place that was labeled for the crackles and pops. The default one is intense which is a little intense for me lol. I wish I could have gone with the medium. But I like it and it really woke this car up. I would recommend

    Awesome tune! Extremely happy!

    Posted by Roberto molina on Mar 7th 2019

    I was thw fence at first but boy am i glad i got this tune. Ive owned the car for 2 years and drive it 40 miles EVERY day and it has never drove this smooth and civilized, until i hit the gas that is. It absolutely blew me away just how much power the car has, its very surprising. I am extremely satisfied and highly recommend. Oh, and the 2-step is nuts too! Trent took care of any questions i had and answered my messages promptly. Again, highly recommend.
