2.0T Tiguan STAGE 1

Boost Dynamic Tuning’s Stage 1 ECU calibration safely unlocks the hidden performance in your Tiguan, delivering gains up to ~250 HP & ~300 WTQ on 93 octane with a smooth OEM+ powerband. Power comes on clean, predictable, and strong—without sacrificing daily reliability.

CRACKLE POPS (OVERRUN)

Also known as overrun. On decel from higher RPMs or when free-revving in neutral/park, you’ll hear sharp crackles/pops from the exhaust/downpipe. (Harder to hear on stock exhaust.) It adds the perfect bit of spice to your Tiguan’s tone.

BOOST CONTROL

Factory boost control can feel uneven and lazy. BDT’s Stage 1 tune reshapes the boost curve for crisp throttle response, linear torque delivery, and repeatable pull after pull.

POWER GAINS

SEO Gains Summary: Stage 1 Tiguan 2.0T tune adds ~65+ HP and ~80+ TQ over stock on 93 octane with improved response and boost control.
