No offense to you or SGP for doing the work, but if it was me I would have used that money for something else. I'm about to make the more common upgrades to my TT, and I'm thinking about SGP too, but I couldn't appreciate even half of that for just one motor. Someday I'll have kids, and I want to save money so that they can go to college. It would be a shame if they couldn't go because I wanted to drive faster.
