Why does ECS tuning say that the seimans 380cc injectors are not compatible with the APR stage 1+ software. Why is that?? Anyone know? I was planning on pairing that combination next year, but that kind of put a halt on those plans. Id appreciate some light on this. Thanks!

 

probably because they want you to pay the way over priced 225 injectors. They are the same flow and spray pattern, shouldnt have a problem

 

I have 99 audi and they said that the 225tt injectors will fit does any1 know where I can gwet some

 

usrallyteam.com, still way overpriced when the siemans are just as good
