Certainly more important than worrying about increasing the size of the intake hole by an inch or so. Just my 2c.
As I'm not sure if that's possible I have concentrated on what I know to be important for getting alpha-n to work well which is to have a good supply of cold air and making sure the IAT probe reports this air temperature accurately (i.e. not suffering from any heatsoak to give false readings for the table).
I look forward to seeing your headlight/carbon tube mod and the results you see from it...

While I don't think it's impossible to hack the MSS70 to run a MAP sensor, I don't think it's really necessary. MSS70 should be able to do alpha-n much more reliably than the MSS54 in the M3 if tuned properly. A big factor in that is the fact that the Z4M uses wideband O2 sensors unlike the M3.
