MAF meters and open-loop.

[LS]

1. MAFs are accurate with Turbos.

2. at the lean point you are probably reading full scale on the MAF,
    your computer responds by going to the internal tables. Which
     would create severe lean condition under boost.
    I do not need to tell you that it is dangerous.
3   You will have to make sure that you have an adequate fuel 
     supply beginning with your fuel pump, and ending with injectors.


   Good Luck
