2000 - 2001 GTI JETTA GLI Golf 1.8T Stage 1 AWD

Unlock Real Power in Your 1.8T — Boost Dynamic Tuning Stage 1 AWD Tune

Stop driving a detuned sleeper — it’s time to let that turbocharged 1.8T eat.

At Boost Dynamic Tuning (BDT), we build hard-hitting ECU calibrations that transform your car from stock and soft to snappy, crackly, and full of attitude. Every tune is dyno-tested and street-proven to deliver that extra punch, razor-sharp throttle, and pure turbo excitement.

No guesswork. No weak files. Just real performance — the kind that sounds wild and pulls even harder.

This is the tune your 1.8T should’ve had from the factory.

Award-Winning 2-Step

Our signature 2-Step Launch Control is legendary — the loudest, hardest-hitting, fireball-spitting anti-lag around. Get rowdy, make some noise, and show everyone why BDT dominates the tuning scene.

Crackle Pops (Overrun)

This feature lights up your exhaust with aggressive pops and bangs when you lift off the throttle or rev in neutral. Stock exhausts get a subtle snap — upgraded setups unleash full fireball mode.

Boost Control

Factory boost control feels uneven and sluggish — we fixed that. BDT’s Stage 1 tune delivers smooth, consistent boost and sharper throttle response for a linear pull that doesn’t let up.

ECU Tune Modification Requirements

NOTE: If you have an upgraded turbo (like a K04), you must purchase our Stage 3 Tune.
