Product Details
Get the full performance out of your 2.5L engine tune on automatic transmissions with IE's TCU tune for all VW MK5 & MK6 2.5L autos. Unlock the higher RPM range for Stage 1 and Stage 2 Intake Manifold Tunes and let that 5 cylinder breath. Enjoy increased power, higher RPM limit, and faster shifts with optimized and adjustable shift points.
Features:
- 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
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. The IE intake manifold is a popular upgrade for owners looking for the full power potential from the stock 2.5L engine. Until now, the power was completely limited to manual transmission cars only as the automatic trans would shift before the power gains in the higher RPMs could be utilized. Now you can join in the fun on your own automatic 2.5L vehicle and rev happy adding up to 47HP & 38TQ when paired with an IE Manifold & Stage 2 Tune! (IE Manifold is not compatible with vehicles equipped with hydraulic power steering)
