Description

2000–2006 Audi TT MK1 1.8T (AWP) Stage 2 ECU Tune

Stage 2 = How the Audi TT Should’ve Come From the Factory

Remote OBDII Flash Dyno-Tested Daily-Drivable K03 / K03S Power

The MK1 Audi TT 1.8T was built to handle more — VW/Audi just never let it. BDT Stage 2 unlocks the torque, response, and boost control the chassis always deserved.

With proper exhaust flow, the K03 finally holds boost instead of falling flat. Sharper throttle, harder midrange, and a pull that doesn’t fade.

No generic files. No lazy torque caps. This is a Boost Dynamic tune built to rip — coupe or roadster.

AUDI TT MK1 1.8T (AWP) — STAGE 2

Stage 2 is where the MK1 TT stops feeling “quick” and starts feeling properly fast.

Expect up to ~265 WHP / ~285 WTQ on 93 octane with required hardware. That’s real turbo shove — not brochure numbers.
