I've got it on my daily driver coupe quattro. I've been running it for 10,000 miles or so. Definitely livens the car up. It feels like what the car should really have had from the factory. Makes me wish the rallx car had a bit more power. I'll agree that there's a bit lacking by the way of low end torque. And 7psi leaves you wishing for a bit more up top. But for a daily driver it ramps up the fun factor ten fold.
I helped a friend of mine install it while he owned the car. He also installed a 3 inch exhaust at the same time. This created a flow issue with the wastegate. The internal wastegate wasn't able to hold 7psi (overboost). I've since installed an external wastegate and open dump tube (lazyness and lack of room), as well as a factory s2 intercooler. I still get the occasional CEL when cruising down the highway. Pulls timing, which is very annoying, but I've been too busy to look into it.
That said, I've also got a 3B swapped car. Having experienced both worlds, I'd say go 20vt if you're in it for the long haul. And if you're looking for easy install and just a much better than stock driving experience, I'd go 7A turbo.
