the large duration cam and speed density incompatibility is way overstated. Yes, if you have one of the "self learning" systems, they will not "learn" how to behave.

With megasquirt, you can simply close the window on the self adjusting below 2000 RPM and manually tune those areas. You will need to run a little rich at idle, but not so much it'll load up.

If you have any electronics background, you can make a much nicer harness that actually fits, and save $600 soldering the ECU up yourself.

I haven't fallen into the bigger is bettertrap. MS2, batch fired for me thanks. My 427W doesn't have 4 cams with variable valve timing and multiple boost controllers. Just fuel, spark and control the fan.
