I don't know what you mean by a 8.5-14.2 psi spring. The springs I know of don't have a variable constant...but I don't know if the GT WG has this option.

if the WG spring is 8.5psi, then the lowest boost you can run is 8.5psi
if the WG spring is 14.2psi, then the lowest boost you can run is 14.2psi

how high you can go depends on your boost controller.

Not entirely true, depending on manfold design and a few other details if you run say a 10lb spring I wouldn't run more than 15lbs. You will start to get oscillations with the WG and hence the power delivery. Try to stay within a few psi of spring pressure for a good solid curve.
