fmu? 3 bar map?

How would you hook up a fmu on hp tuners for a turbo

If you have a fmu is that doing the same as a 3 bar map sensor or do they have to be used in conjuction?

running rich? turn the boost up

An FMU is nothing like a map sensor. It's a mechanical device that increases fuel pressure according to air pressure.

Yes. I'm aware of that. But would I have to run a map sensor along with that to tune for it

Okay, thanks I think I'm understanding but how would you fine tune your injectors for a right a/f? Would you be able to change the injectors look up tables or is this a pretty much a only a simple not precise way of tuning?

Take it to a professional... I have read quite a few threads/posts of yours and I am convinced you reay have no clue.
