cam gears for VQ37

didn't some of the members with FI and headers complain about no power gains because of exhaust cam and VVEL overlaps, these might help in getting back that power. But

But here's a thought, aftermarket intake cams already exist for the previous gen VQ's, why not make the VVEL run to the similar the specs of those cams??

The lose of power was the top end, basically the top 500RPM, the rest of the power band showed an increase.
Now, will this give back that little boost on the top end? I am not sure, I have not done enough research on VVEL and how the system controls and modulates it control.

FI Headers lean out your A/F pre-tune so people lose power. But after being tuned to that mod, you regain your power back.
