Live in one of those countries where they tax your car based on the engine's displacement, or where boring old diesel is cheaper than fun-loving petrol, but crave a large vehicle like the Audi Q7? The diesel V-6 probably wasn't your dream engine, but JE Design can help with that.

Leingarten, Germany, based JE Design has had a look inside the Q7's engine computer and found some extra ponies and torques sitting around not being used, so being the compassionate lot they are, they set them free. Give them three hours with your engine computer and they'll add 52 horsepower and 37 pound-feet of torque with a few taps of the keyboard. Suddenly, your hum-drum 233-horsepower 3.0-liter turbodiesel with its 369 pound-feet of twist is a more sprightly performer with 285 horsepower and 406 pound-feet.

Sure that doesn't sound like all that much oomph compared to a flashy Q7 3.0T, what with its supercharged petrol V-6, but it'll get you in the neighborhood. Instead of dawdling around for 9.1 seconds on the way to 100 kph (62 mph to us Americans), you'll get there in a more respectable 8.4 seconds. It ain't an R8, but taking 0.7 seconds off the zero-to-60 (100 kph) for a 5000-pound (2270 kg) vehicle is no small feat. JE Design has even managed to raise your top speed from 210 kph (130.5 mph) to 219 kph (136 mph) so that the right lane on the Autobahn won't feel like as much of a penalty.

Of course, JE Design isn't just giving this stuff away. If you want that power liberated from your engine computer, you'll have to fork over 1499 euro (about $1950 to us dollars and cents folk based on current exchange rates). They'll even throw a one-year warranty on the engine for another 199 euro (about $260) and you can extend the warranty an extra year if your Q7 is less than two years old and has less than 100,000 kilometers (62,137) miles on it. Pricey, yes, but not all that bad considering you don't even have to bring your Audi into the shop. Just mail the computer over if you don't have time to swing by Leingarten on your way to Leipzig.

If you're the conservative type, you can stop there with only 1698 euro ($2210) out of pocket. For all you flashy types, though, JE Design has much, much more to offer. After all, it wouldn't be a German tuning company if they didn't offer an outrageous body kit. All manner of dress-up bits are available ranging from the mundane 99 euro ($130) headlight covers to the wild 2699 euro ($3500) 12-piece widebody kit. Let's not forget the 690 euro ($900) front spoiler covers, the 1798 euro ($2350) rear fascia with quad exhaust and the 1099 euro ($1450) rear spoiler and C-pillar covers.

And that's just the body. You'll of course want the 1428 euro ($1850) electric lower system that can drop the vehicle 1.4 inches to reduce drag and the sweet graphite-silver five-spoke wheels, which will run you another 5190 euro ($6750). Make sure you get the 49 euro ($65) steering limiter, though, or your fancy new wheels are going to rub on the frame.

Go hog-wild on all the upgrades both under and above the hood and you'll be laying down some 14,750 euro ($19,170) on top of the minimum 53,300 euro ($69,220) with VAT you paid for that Q7 with 3.0-liter diesel to begin with. If 68,050 euro ($88,375) -- VAT included and assuming you bought the cheapest Q7 3.0 TDI you could get your hands on -- is too rich for you blood, you could always just stick to the power upgrades and be out only 54,998 euro ($71,450). Or you could make peace with the fact that a 3.0-liter diesel isn't a performance engine and stick with the cosmetic upgrades only for a total of 66,352 euro ($86,185) and hope no one challenges you to a race. As for us, we'd opt for the former rather than the latter.

It's a fair bit of coin for sure, but you do get a TÜV certificate out of it so you won't have any trouble registering your creation. Of course, we're assuming all of these prices already include the 19-percent Value Added Tax, though JE Design's press release only specifically mentions the VAT in the engine upgrade pricing. We're also hoping that these prices include installation, as the press release doesn't mention that, either.

What say you? Does this design torque your heartstrings, or are you better off leaving well enough alone? Sound off in the comments below.
