Chip Tuning, C4 Audi UrS4/UrS6 & S2, AAN/ABY Stage 1
Suitable for all AAN/ABY engine ECUs in C4 S4 and S6 and later S2, stock turbo Audis. Uses stock FPR, injectors and wastegate spring.
We recommend this tune for all motors with stock internals, upgraded engine rods or pistons not required. User feedback has been that the chipset feels smooth like stock but with vastly increased power, fuel mileage under light load same as stock.
For users looking to get the most out of the stock K24 turbo, consider our Stage 1+ which uses larger injectors, MAP Sensor and a stiffer wastegate spring, with our Stage 1 on stock injectors this is the farthest the tune can be pushed before running beyond the safe limits of the factory injectors.
Dyno Chart shown below is a bone stock car with only our chipset and a 3" exhaust. This car picked up an additional 15 WHP.
Dyno Proven 205 WHP & 224 WTQ (Gains of 23 WHP & 32 WTQ Over Stock AAN)
Note: We now only ship chips which can be installed by the user or an ECU specialist, we no longer offer the service of shipping in ECU's and modifying them.

i can't believe how smooth it is. WAY WAY smoother than my mothers IA3 on
her car. it sure feel like it reaches peak boost sooner. it is fairly
deceptive. u don't realize how quick it builds speed as compared to the
older mapping on the IA3. honestly, the older chips feels horrible
compared to the newer design.
