Sorry for repeating the topic, but i can`t find a clear answer anywhere.
So, t3\t4 hybrid turbo is dead, i`ve ordered gt28rs. The question is if i can use gt28rs with stock ECU and stock chip? I`m worried about exhaust tempereture: it seems to me that on high revs it can be higher than usual because of the poor mixture and turbo will be destroyed because of that. Is such situation possible or everything will be okay because of the airflow meter?

P.S. Or is it better to use S-AFC II with it?

Thanks.

You can use the stock ECU, almost everyone does. I wouldnt just bolt a huge turbo onto a completely standard car though, I'd also want a free flowing exhaust, uprated fuel pump, FMIC, induction, etc etc
