As far as stock cam goes, when boosting I have seen positive results increasing higher rpm and higher airmass areas by 5 to 7 percent.

SOI is the key to making power in these cars, and properly dialed tables.
As far as "cam timing" most if not 99% of the cams made for these cars are made for "0" on the cam table. Any change usually results in MORE boost, and LESS power. (aka: flow issues)
