Low boost fuel management

As I'm planning to turbo my tiny Honda (1.4 engine

) I was looking on this site for fuel management opinions.
As I'm planning to run low boost (6psi), as far as I've seen an 12:1 FMU (Vortech one) would suffice with stock injectors, and hopefully even stock fuel pump would suffice too (needs to be tested tho).
Now comes in play Map sensor which'll make ECU go bezerk after it detects pressure.
Is only way to fix that missing link, or is there any other way?
Do you think, as said for such low pressure, those two (Vortech 12:1 FMU and missing link - or something else) would be OK for fuel management?
Will I need to retard timings aswell, or will stock timings do?

Re:Low boost fuel management

i think a 12:1 might be too rich for a 1.4L. maybe a 10:1.

make sure your pump is ok. you could use a MSD BTM for extra spark and timing retard under boost only. The missing link is a good choice. make sure it is an AUTHENTIC one though.
