It's been awhile since I read up on forced induction and cam profiles that work with them. But if I am remembering correctly, such a cam is cut with high opening and closing rates with little LSA. The LSA is not needed because you are not relying on the air's mass to move it ( which NA relies on). The boost pressure does the work for moving the air.

I also think that the cam lobes are not as fat and do not stay open as wrong. They might have shorter durations.

As I said, it's been a long time since I read up on all this so someone correct me where I am wrong.

Hi McM1984, you really should get a tune that includes the M90
and the Hot Rod cams. No motor damage if you only have the
M90 tune, but it probably will not run as smoothly.

you'll want FI cams for it, or extremely mild N/A cams. If you start going wild with overlapping N/A cams, you can cause serious problems with an FI system.
