Will this let you adjust the intake cam more than the factory electronically or will you have to manual adjust then use the range of adjustment from the factory to get more adjustment?

You’ll have to manually adjust the cam gear. This essentially lets you degree the intake cam. The factory 20* advancement cannot be changed, as I believe it is a mechanical limit. I do not think I would want more than 20* either, as that factors in more complexity with tuning, the VCT unit and would probably require it to an electric gear to really dial it in.
