One of the virtues of owning a modern car is the fact that, if you want extra power under the hood, you might not even have to open the hood to add some. Re-flashing a vehicle’sECU(engine control unit) is often as simple as plugging a computer or specialized programming module into theOBD port, turning the ignition on, transferring the new code into the ECU, and hitting the road with newfound oomph. It almost seems too good to be true, right?

Well,Chris Harrisis known for his healthy skepticism with regards to most things automotive. So he wasn’t expecting the guys fromREVO Technikwould be able to do much with his new-to-himAudi S4 Avant. But as you can see in the video above, theREVOgeeks were able to turn Harrismonkey’sAudiwagon up at least one notch (the same notch as a new, much more expensiveRS4 Avant, as it turns out), simply by rearranging some zeroes and ones. We’ve said it before and we’ll say it again: These are the good old days.
