⚙️ Boost Control Recalibrated

The factory GTI boost curve can feel sluggish and inconsistent. BDT rewrites the boost logic to deliver a smoother, more linear ramp, instant throttle engagement, and consistent power through every gear. This isn’t generic tuning — it’s precision-built calibration that transforms how your GTI drives.

Crackle Pops (Overrun)

Add serious auditory character to your GTI with selectable overrun/crackle behavior. Designed with OEM-level safety logic, active only in Dynamic/Sport mode or per-map if requested.

• Selectable Low / Medium / Intense levels
• RPM-dependent activation windows
• Subtle on stock exhaust; aggressive with free-flowing systems
• Automatic safety reduction if EGT climbs too high

MULTI MAP SWITCHING + RAL LIVE

Dyno-Verified Power Gains

Typical results on 93 octane with healthy hardware. Actual gains vary by dyno type, altitude, fuel quality, and heat-soak. BDT publishes live before/after runs for transparency.

ECU Tune Modification Requirements

Stage 1 is designed for stock turbo/hardware, but supporting upgrades improve consistency and safety.

Multi-Map Layout (Adjustable on Request)

IF YOU WANT YOUR CAR TO SURVIVE, THESE MUST BE DONE!

We want your GTI to live a long, happy tuned life. The items below are based on years of tuning MQB cars. If these aren’t kept up, failures happen — and it won’t be the tune.

FAQ

• Is Stage 1 safe on a stock MK7 GTI?
  Yes, Stage 1 is designed for factory turbo/hardware with OEM-style safeguards and torque modeling.
• Do I need a TCU tune?
  For DSG cars, a TCU tune is highly recommended to optimize clutch pressure and shift behavior for added torque.
• Can you adjust maps for my fuel or climate?
  Absolutely. We tailor maps for your fuel quality, elevation, and weather while keeping safety limits in place.
• How do I flash?
  You’ll flash through the OBDII port using a Windows laptop and BDT Remote Flashing Suite.
• Will crackle pops hurt my car?
  The feature is controlled, RPM-windowed, and EGT monitored. It can be disabled per-map if you prefer a quieter setup.

Late Policy: If you book an in-person flash and arrive late without notice, a $50 fee applies. Reschedules must be made at least 1 hour prior.
