[200q20v] RS2 & 3B - Fueling Around

If your statement is true, how do you explain the
driveability problems of those individuals who played
mix n' match with RS2 components?

Simple fact that RS2 injectors are designed to run at
a different pressure than 3B injectors- without a
matching FPR, how are you going to obtain the right
amount of fuel? It will either be too rich or too lean
based on the same electrical input.

You're changing the situation if you're implying that
I am only talking about a max boost situation where the
fuel system is running closed-loop- I'm talking about
all across the board, as we don't run our engines at
max throttle/boost all the time, do we?

I don't really understand what you're talking about in
terms of flow being the same at a fixed boost level- how
would a larger turbo produce the same amount of boost
w/o more airflow? I thought that you would have more airflow
through the larger turbo, causing the effect that you would
have more air physically flowing into the intake at the same
boost level as the compressor would be able to compress more
air at the same pressure due to the larger size. If turbo boost
is measured as absolute airflow through the intake manifold
(which I think you're saying), then that makes sense to me and
I'm totally wrong about turbocharger operation and I stand

I don't want to spread misinformation, sorry if I did.
