Shouln't it be a matter of time when dual injection is coming to America? Anyway, the difference is easily visible. Just look at the intake manifold.
While very most ROW/Euro spec EA888 3G used to come with dual injection mine does not, since it's a 2018 7.5 Performance (engine code DLBA, 245 HP). Both the CHHA and CHHB (2012 - 2018) are dual injection. My tail pipes are still stunningly clean, even though it doesn't have a PF or dual injection or both. It wasn't the case on my previous GTI, even though it came with dual injection. You see, sometimes things aren't that easy. That said, my Mini Cooper's tail pipe is black even though it's got port injection only. I'm sure on a T-GDI there's some correlation between tail pipes and likeliness of IVD issues, given that the car has no particulate filter.
