It's the later spool that's helping you. Mine is a T25 manifold, so it spools even quicker. I've been tuning (or trying to) tune a friends T3 GT3071 on an FSI and it spool a lot later than mine. With that being said, it gets like 100% traction in third and feels fast as hell.
I pedal the shit out of it and can get around it. I over exaggerated a tad, I can get a decent amount of traction in 3rd in probably 70 degree plus weather, but it still spins. 2nd gear could start a forest fire any way you twist it though. These tires work really well when it's warm, and really bad when it's cooler.
Edit: I'll be lining up against said FSI in he next few weeks and can let you know what kind of differences I see. I'm 99.99% sure my car makes a decent amount more power than his, but we'll see.
