In response to 68wfo

Is your system TBI or MPFI?

I have the C950 MPFI on a 454 BBC (in a C3 vette, BTW). I have to run VERY low AE vs MAP values to avoid drowning the engine. single digits to the left, about 25 to the right.

But I'm told TBI requires larger values.

This also depends on the size of your injectors. Small injectors would need higher values. My injectors are 42 lbs/hr.
