This Audi S3 stopped in for a stage 1 APR flash tune. The owner was in previously to get Rotiform KPS wheels and was back for some power this time. This simple upgrade requires no engine hardware modifications, and produces 357-381 HP with 349-392 FT-LBS of torque. The tune gains as high as 66-93 HP and 68-109 FT-LBS of torque, making the S3 exceptionally quicker in all scenarios.

The upgrade is offered in both high and low torque versions, and is available for various fuel grades. The high torque upgrade may require an upgraded clutch, or APR's TCU Upgrade to avoid clutch slip, so low torque software is available, offering an impressive 349-366 FT-LBS of torque.

To get the most out of the power, the vehicle can be outfitted with an upgraded intake, intercooler, catback exhaust and other small modifications without requiring any new modification to the ECU. For those looking for even more power, check out the APR Stage 1 ECU upgrade. APR recommends using colder heat-range spark plugs (Ex: NGK-R7437-9), properly gapped to a tighter gap (Ex: 0.024" ±0.002" or 0.6mm ±0.05mm), properly installed and torqued (Ex: Per the manufacturers specifications), and maintained with a shorter changer interval.
