IE Performance ECU Tunes For Audi B9 2.0T Q5 (80A)

ECU tune really makes a difference.

After flashing the tune, which by the way is straight forward, the change is notable upon accelerating. I love the strong pull right off the line. Easy to change octane ratings if needed. My only disappointment is the transmission tune for my Q5 is not compatible as I have the Gen 2 TCU variation . Cold air intake may be next.

Great product!! The way Audi should let their cars come out of the factory!

Would definitely do it again in a heartbeat! Love my Tune!

Great product

It took a few times for the app to stay connected to the tuning module, but after it connected, it took about 20 minutes for the tune to flash. What a difference! Much better throttle response, more low end "grunt", and a very noticeable increase in power. IE makes a great product!
