Before you jump on the tuning bandwagon, make sure you go to reputed professionals who can provide a safe, effective remap to prevent any undesirable effects on the engine.

"Tuning can be as vital as any upgrade you consider; it unlocks potential that's often hidden beneath the surface."

Each of these performance upgrades can significantly elevate the driving experience of your 2001 Audi S4, adding that extra flair to your ride.
