With some modifications you can probably make 500whp or more with the 2G MAS, whether is be more hacking of the unit itself, adding a bypass filter, or ignoring its output past some point. DSMLink has functions built right into it to get around MAF overrun. Blaha ran 10.5 on a 1G MAS, throw one of those on there.
I prefer no MAF/MAS at all.
