BDT Stage 2 ECU Tune — 2009–2014 VW Golf R (MK6 • EA113 2.0T • K04 • AWD)

Take your MK6 Golf R to the next level. With Boost Dynamic Tuning’s Stage 2 ECU calibration, your EA113 K04 comes alive with explosive midrange torque, smoother power delivery, and dyno-verified gains up to 340+ WHP and 370+ WTQ on pump gas, and even more on E30 blends.

Why Upgrade to Stage 2?

Stage 1 already wakes the Golf R up—Stage 2 pushes it to true street-weapon status. By optimizing fueling, boost, and timing for a freer-flowing setup (downpipe + intercooler + intake), Stage 2 unlocks the full potential of the factory K04 turbo while maintaining daily driveability.

Stage 2 Tune Features — Golf R (K04)

• Dyno-Proven Power — ~340–350 WHP / 370+ WTQ (93 octane); ~360+ WHP / 390+ WTQ (E30 blend)
• Refined Boost Control — smoother curve, less lag, harder pull to redline
• Raised Rev Limit — safely extended to maximize top-end power
• Torque Management Optimized — stronger midrange while protecting drivetrain
• Overrun / Crackle Pops (MULTI MAP SWITCHING adjustable intensity/RPM)
• 2-Step / No-Lift Shift (Manual only) • DSG Optimization with BDT TCU tune
• Fuel & Timing Maps Optimized for higher flow + stability on upgraded hardware
• OBDII Flashing — load from your laptop, no ECU removal

Dyno-Verified Power Gains

Numbers vary by dyno, mods, and fuel quality. BDT provides live before-and-after dyno proof.

• High-Flow Downpipe (required)
• Front-Mount Intercooler (required)

• Aftermarket Intake (strongly recommended)
