Project Car: 2018 Audi RS3 - ECU Flash Stage 1 - APR 2.5 TFSI EA855 EVO ECU Upgrade

Project Car: 2018 Audi RS3 gets some more power!

 At first I was skeptical like most, as in I didn't want to flash the car due to warranty issues etc.  But that seems to be the case with me on just about all my cars, the thought that I might keep this one stock LOL... but the mod bug just seems to always come back harder!  The logical most economical mod in most cars tends to be the flash tune to stage 1, biggest bang for your buck at $999.99.

APR states 86 HP and 108 FT-LBS and boy do you feel it from 2nd to 3rd the car pulls very strong.  My first 100 miles or so were a blast!  I would recommend this tune to just about anyone that has this car that is not afraid of voiding your warranty. 

APR Stage 1 - 

APR’s ECU Upgrades are the best dollar-per-horsepower modification one can make to the 2.5T engine. The upgrades dramatically increase horsepower and torque, making for an exceptionally quicker and more exciting vehicle. This is made possible through APR’s optimization of the factory engine management system to take full advantage of the engine’s capabilities, without needing any end user adjustment. The software loads to the factory ECU through the OBD-II port, resulting in a clean and headache-free install. Optional features, such as APR's EMCS Program Switching and APR Mobile are available. Furthermore, for those looking for tuning with a limited powertrain warranty, APR Plus has you covered!

The APR Stage 1 ECU Upgrade is the first step towards making more power! This simple upgrade requires no engine hardware modifications, and produces 459-542 HP with 451-506 FT-LBS of torque, depending on octane. Gains as high as 66-132 HP and 88-146 FT-LBS of torque are available throughout the power band. To get more 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. Upgrading the small factory intercooler is highly recommended on this platform.
