Introduction

This daily driver is a spirited torquey ride. The cosmetic upgrades add to the car’s sleeper persona. However, the tuning really packs an all-wheel drive punch. On those occasional track days, the tuning really shines. Before the latest APR ECU version update and the TCU tune, the S4 could regularly beat even most tuned V-8 muscle cars, even a stock Hellcat. Anxious to engage launch control for some passes this spring to see what the new ECU version update a TCU tune can do.
