Chip Tuning, Audi 80/90/Coupe Quattro, 7A 20v Stage 1

Wake up that sluggish 20v!

This chipset is a direct upgrade for the stock 7A engine. Substantial power gains in the midrange make for a much broader powerband.

We have software for both the early (2 connector) and the later (4-connector) ECU. Select your ECU type above before checkout.

Please Note:

• If your ECU is already socketed, then we can ship you the Chip Tuning Package to install yourself with included instructions.

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.

**Not for use on emissions controlled vehicles in California, off road, track, and racing applications only**
