2.0T AUDI TT STAGE 2

Boost Dynamic Tuning’s Stage 2 ECU calibration methodically increases performance with gains up to ~295 HP & 330 FT-LBS (93 octane), without sacrificing drivability or reliability. Our calibration efficiently and safely maxes out the factory turbocharger’s potential.

CRACKLE POPS

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.) Add the perfect bit of “spice” to those already tasteful exhaust notes.

BOOST CONTROL

From the factory, ECU boost control can feel bumpy and uneven during long pulls across the powerband. BDT’s Stage 2 tune refines and smooths the boost curve for crisp, repeatable power when you push your Audi TT to the limit.
