  • Question

    I had this program uploaded in my 2001 Audi TT 1.8t today from a company called Dubwex in Cincinnati... The car went from stock 8 psi on boost to about 12 psi and is now stuttering really bad when it hits 12???... Any ideas as to what might be going on with it?

    By Jason Ellis on February 7, 2023

    Answer
    On a car of this age, you'll want to look at things like spark plugs, ignition coils, injectors, and have them check for boost leaks.

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.

APR Stage 1

The APR Stage 1 ECU Upgrade is the first step towards making more power! This simple upgrade requires no engine hardware on modifications on most models and on pump fuel produces 196-204 HP with 240-242 FT-LBS of torque on the 150 HP engine. The 150 HP beetle engine produces 183 HP with 220 FT-LBS of torque, but the APH engine code requires a 4 bar fuel pressure regulator. The 180 HP models produces 209-215 HP with 242-247 FT-LBS of torque. Lastly the 225 HP model produces 257-263 HP with 264-267 FT-LBS of torque. To get more power, the vehicle can be outfitted with an upgraded intake, catback exhaust, and various other bolt-on modifications all without requiring any new modifications to the ECU.


APR Stage 1 is available for 91 AKI, 93 AKI, and 100 AKI fuel in North America and 95 RON, 98 RON, and 100 RON in the Rest of World.


APR Stage 3 K04

The APR Stage 3 K04 ECU Upgrade is the next step towards making more power! This simple upgrade requires an APR K04-001 drop-in factory turbo upgrade, and a 4-bar fuel pressure regulator with no other engine hardware modifications and produces 242-245 HP with 268-275 FT-LBS of torque. To get more power, the vehicle can be outfitted with an upgraded intake, catback exhaust, and various other bolt-on modifications all without requiring any new modifications to the ECU. While not required, a race DP is highly recommended. This stage is not available for the 225 HP model as a K04 comes standard on those vehicles.


APR Stage 3 K04 is available for 91 AKI, 93 AKI, and 100 AKI fuel in North America and 95 RON, 98 RON, and 100 RON in the Rest of World.
