Hi
you cannot do nothing with standar injector due to the fact that this kind of turbo "lives" at a minimum of 1.2bar ...and at 1bar with this td05,you canot reach the perfect AFR ...
I have tried td05-16g from scooby, and some KAMAK STS,but i prefer a td05-14b from greddy or some Garrett gtX ,meanwhile stock td05-16g are very cheap
