2003-2005 1.8t B6 A4 Stage 3 Multi-Map (Map switching) Tune

The tune is optimized for a 4-bar MAP sensor, ID 1050cc injectors at a base fuel pressure of 58 psi, featuring a GTX3584 turbo, VR6 throttle body, IE intake manifold, 3651 CAT cams, and a Full Race exhaust tubular manifold. Configured for a 44mm Tial wastegate equipped with a 15psi spring.

This tune offers three modes: Pump gas, a mixed fuel option, and full E85. Results indicate impressive power outputs—630 wheel horsepower at 32psi on E85, 540 wheel horsepower at 26psi on a mix of E40, and 460 wheel horsepower at 20psi on pump gas. Notably, the tune operates in a MAFless configuration.
