Integrated Engineering Product Description

Stock transmission tuning on the automatic VW 2.5L engines limits the RPM range and greatly reduces the available power of your rev happy 2.5L 5 cylinder engine.  IE's TCU tune has been carefully set up to offer you the full performance benefits of ECU tuning and hardware upgrades such as the IE Intake Manifold by safely increasing the available RPM limit.

The result is a fully unlocked power range offering the entire performance capability of the 2.5L engine on your automatic transmission.


  • Unlock higher RPM limits on 2.5L automatics
  • Higher shift points of 6800 or 7100 RPM
  • Allows the use of the IE Intake Manifold on automatics
  • Perfect match for Stage 1 or Stage 2 ECU Tunes
  • Flashed directly through OBD-II Port (No TCU removal required)
  • All safety and reliability features retained

What's Included:

  • Integrated Engineering AQ250 Transmission Tune
  • IE PowerLINK V3 Flash Cable (OPTIONAL)
