Default Has anyone tried Unitronic ECU Tuning

I was thinking about trying this for my 2005 A8L 4.2.. They say it brings the hp up to 356 and a local shop will download it in 20 mins for $500. I was wondering if anyone has tryed it on here.

I've had it done. Worth every penny. Especially nice no longer having the silly 130 MPH speed limiter.

Any effect on fuel economy?

For me, no change positive or negative. And, I've logged all fuel purchases for the past eight years that I have had the car.

I realize that the power and torque increase is probably not noticeable, however, how is the general drivability? Is the throttle more responsive and is the get up and go better?

This is the most noticible result from reprogram. Unless there is a turbo.

This is something that the Unitronic tune made possible this past Summer at the Bonneville Salt Flats...
