MK4 STAGE 2 ECU TUNE

Experience the thrill of unparalleled performance with Boost Dynamic Tuning’s Stage 2 ECU calibration, expertly engineered to deliver up to 265 Wheel HP and 285 Wheel TQ — without compromising drivability or reliability. Our calibration safely and effectively unlocks the full potential of your factory turbocharger.

AWARD WINNING 2 STEP!

Rowdy, fireball-spitting, true anti-lag vibes. If you want chest-thumping 2-step, this is it.

CRACKLE POPS

Also called overrun. Lift at higher RPM or free-rev in neutral/park and you’ll hear spicy crackles and pops (quieter on stock exhaust).

BOOST CONTROL 

Factory boost can feel bumpy and lazy on long pulls. BDT Stage 2 smooths the curve and sharpens response so it surges cleanly through the powerband.

Immobilizer Delete

If you’re running a plug-and-play ECU, we can provide an immo-off option so your car starts without PIN matching between modules.
