only things really to detune are , (i'm assuming there is a drivability problem)

fuel and spark. timing should 10* for stock, stock plug gap is .052 , but i like .040 (but i spray)

make sure fp is about 32 psi fatter is fine, but leaner is bad.

so what is the issue your having? and you can't port the maf , just upgrade it, but unless you have heads or a power adder it won't do anyhting. plenty of airflow to support about 300 true hp. same goes for the intake.
