I'm tuning the engine, it's a 13 BREW (92 twin turbo) that I'm
running as normally aspirated. I think I might need to reduce
the injector rate on Tracy's EC2, since his factory setting is
for the normally aspirated injectors. On the normally aspirated
engine, both primary and secondary injectors have the same flow
rating. I found that my injectors are 28 lbs for the primary,
and 40 lbs for the secondary. Does anyone know what a normally
aspirated 13 B,  say a 1988 engine has for factory injectors?

I'm finding that I'm running rich, I can't seem to lean out the
setting enough in mode 1,  and might need to change the
injection rate in Mode 3 on Tracy's controller.

How and where are you monitoring the intake manifold pressure Brian?

Try turning down the fuel pressure regulator. What pressure do
you have it set for now?
