With a carb, you have pump squirter's. When you step on the gas pedal, they give an extra squirt of fuel for the added load. EFI needs something similar. I have a separate map based on vacuum load and rpm. When the vacuum goes down, the computer adds extra fuel. Seems to work pretty well.
You'll need to look and see how the ECU manages air pressure changes. I'm not really familiar with that system, but it must be able so sense and adjust for ambient air pressure. If your AFR is correct during steady driving, it's probably fine, and probably not your problem.

I synced all the stacks. The Fast 1.0 has an accel setting to up the fuel for
acceleration, I have been slowly upping it, no change. The system is supposed
adjust and learn for altitude changes. I just bought the car, the 8 stack system
was set up by Imagine FI in AZ, I have talked with them a few times and was
told it should adjust for altitude.
What I don't understand right now, am about to call FAST, is why the AFR
settings I put in are not what is showing during operation and why it goes
to an AFR of 15.9 when I open the throttle under load.
