APR ECU Upgrade Stages
APR’s ECU Upgrades are available in multiple octanes levels. Each stage is fully compatible with an upgraded intake, catback exhaust, or other minor bolt on modifications.
The APR Stage 1 ECU Upgrade is the first step towards making more power! This simple upgrade requires no engine hardware modifications and produces 290-337 HP with 320-375 FT-LBS of torque on most models. To get more power, the vehicle can be outfitted with an upgraded intake, intercooler, catback exhaust, and various other bolt-on modifications all without requiring any new modifications to the ECU. This stage has an optional low and high torque modes to maximize clutch and transmission compatibility. This stage also has optional FWD and AWD files depending on setup. The FWD files will limit wheel spin in first gear.

Enhance your exhaust note just like Audi’s latest RS models! The APR Exhaust Crackle, lovingly called “pops and bangs” by many, adds a distinct crackle to the exhaust note upon lifting off the throttle, gear changes on a manual, decelerating, or while free revving at a stand standstill. This optional feature is available at no cost, at the time of flashing, for most compatible ECUs at stage 2 and higher stages. For convenience, the feature is only enabled when the vehicle is placed into sport/race mode. Lastly, for safety, this feature has built in hardware protection limits, and will only function when it’s considered safe to do so. We offer this in both a "soft" and "aggressive" mode as illustrated below with our 2019 Golf R featuring a full APR Valved Catback Exhaust System.
