boosting on recal. pcm
if your below the 62lbs/min you can get away with one, though iif you want two good luck on making it yourself, luckly HP tuners will be offering a SD set up soon.
most people would never put the time into having 1 drawthrough on a twin setup.
I have discussed running 1 maf on 1 turbo of a single with some scaling for a ford setup, never tried it, but it could work.
