Doing a a turbo conversion on a 2200 ohv....

As far as tuning is concerned... can I get away with a stock ecm with a rising rate regulator and larger injectors?

You would still need to adjust base pressure. There is one new Cartech regulator that does both, but most don't.
I tried this and my rising rate regulator broke... bye bye motor.

Ahh yes... what you say makes sense. Larger injectors will spray more fuel regardless of boost or not.

So I did some more research on this.... Depending on how much bigger the injectors are, the base fuel pressure will need to be lowered to a certain level to allow a stable idle (not overly rich). However, even so... fuel injectors do not atomize fuel very well at low fuel pressure... especially larger ones.

I would conclude that idle quality, low rpm fuel economy and emissions will suffer... that bothers me.

I think I will be going with the "additional injector controller" method instead... and leave the stock ecm and injectors alone.

WHAT INJECTOR CONTROLLER DO YOU THINK THAT YOU WILL RUN? as i am on this build as well

What year is the car? Your profile is not filled out and depending on the year, there may be much better options...
