Large changes in the MAP table values can do that but you did not say at what point in the tuning procedure this turned up. What have you done or tried so far?

I started up the engine tonight, just to be sure it really worked last Tuesday. Started just fine but there was a
kind of surging of the engine at the lowest RPM. If I increased RPM it started to smooth out. Also increasing the mixture
helped a little, but not a lot.
My question is: is this surging at low RPM indicative of something specific (too lean/rich mixture, injectors not
putting out too little/much). Something like that? I am just trying to get a feel for any general rule when running in that
manner. And if there is no consistency, that's good to know as well.
Thanks,
