Phase 1: Turbo Noises
- Phase 1 parts:
• aFe Magnum FORCE Stage-2 Pro 5R cold air intake – more turbo sound and flow.
• Velt Sport turbo inlet pipe – smoother airflow into the compressor.
• Turbo muffler delete – sharper spool and whistle.
• BOV spacer kit (factory diverter valve) – crisp blow-off noises without touching boost control.
Trunk audio
Trunk audio setup:
• 2× Hifonics HFX12D4 12" subwoofers – handle low-end duty.
• Taramps BASS 800 amplifier – delivers clean power.
• QPower dual 12" enclosure – tuned for tight, punchy bass that still works as a daily trunk setup.
Next: Phase 2 – Accessport, Stage 1 and fuel system
Phase 2 plan:
• Full baseline service before tuning.
• COBB Accessport with EQT Stage 1 ECU tune.
• EQT DSG tune for the DQ250 gearbox.
