According to Car and Driver…
"The SQ5’s engine—specific to North America, since the European SQ5 is a *diesel—is closely related to the 333-hp version in the S4 and S5 (itself an uprated *version of the 272-hp six in the Q5 3.0T). But the SQ5 gets revisions that raise output another 21 horsepower, mostly in the higher reaches of the rev band, as suggested by the 347 pound-feet of torque *plateauing way up at 4000 rpm."
I'm the extra horses are either from a little ECU fingering OR by some performance parts...

The SQ5 has 354 HP, 347 lb/ft, stock. The reason the get more out of it in the SQ5 is because there is more room under the hood to fit a beefier block and better cooling capacity, allowing them to turn up the boost.
There are several after-market ECU upgrades out there that can easily take the power over 400 HP. Additional gains can be had by replacing the SC pulley with a smaller one, or the crank pulley with a larger one. (GMG makes one where the accessory pulley is the same original size so nothing else is over-driven.) My preference would be the larger crank pulley because it increases the surface area of the belt, rather than decreasing it and causing slippage of the SC pulley. It's 7% larger, uses the same belt, and is simpler to replace.
Changing either pulley with result in more low-end power and improved throttle response. However, without the ECU upgrade, all of that additional pressure will be dumped above 5000 RPM. Of course, all of these upgrades will most likely void your warranty. Audi can detect if the ECU was tampered with, even if it was changed back. At least you can neatly replace a stock pulley.
My SQ5 arrives next week. I may do the crank pulley change, just because it's simple and can provide modest gains without destroying my warranty.
