ECU calibration
Stage 1 + Stage 2 Bundle — Audi S4 (B9)
$1054 $1198
Most people who buy Stage 1 come back for Stage 2 within a season, once the exhaust is on. Buying both together costs less than buying them a few months apart, and the Stage 2 file sits waiting on your account until you need it.
What you get now
The Stage 1 calibration and the handheld tool, ready to run on standard hardware.
What you get later
The Stage 2 file, released whenever you tell us the exhaust and filter are fitted. No second purchase, no expiry.
Prices shown are placeholders. Confirm before ordering.
