Audi TTS 8JStage 1 to Stage 4 tuning guide

The first TTS has the EA113 2.0 TFSI with the K04 turbo, the engine in the S3 8P and Golf R Mk6. Audi rated it at 272 PS and 350 Nm from 2,500 to 5,000 rpm in Europe, with quattro and a six-speed manual or S tronic, and recommended 98 RON (Audi UK); US cars were rated at 265 hp and 258 lb-ft (Audi USA). Because the engine is shared, tuners sell the same files and most of the same parts for all three cars.

Parts list

  • Engine tune required APRREVO034MotorsportUnitronicIE

    All of them reflash the factory engine computer.

  • Gearbox tune recommended REVO DQ250 TCUAPRTVS Engineering

    REVO raises the S tronic's torque limit to 500 Nm.

Before you buyREVO notes the S tronic's torque limits are built into its software, not its hardware, so a gearbox tune is part of any full-torque file. Check the fuel pump's cam follower before tuning: Autotech says to inspect the camshaft and always replace the follower with an upgraded pump (Autotech).

Stage 2: Intake, intercooler, downpipe and fuel pump

311–373 PS

With an intake and a high-flow downpipe, 034Motorsport quotes 311 hp, and 315 hp for Stage 2+ (034Motorsport). REVO's Stage 2 (318–334 PS) is written around the stock high-pressure fuel pump; its Stage 2+ for an uprated pump makes 333–373 PS (REVO).

Questions to ask the shop

  1. Is my car a CDLB TTS, manual or S tronic, and which files fit it?
  2. When were the cam follower and the timing belt last changed?
  3. Will you log knock before and after the tune, and is the file written for 98 RON?
  4. Do you tune the S tronic along with the engine?
  5. Will the stock high-pressure fuel pump keep up with this file?
  6. Does the setup keep a catalyst, so the car passes inspection?
