pretty simple to get the DOD to work for ya instead of against ya. In the older GM high tech they did VVT cam swaps and the gains were pretty impressive
They did, but very few people can tune for it. Very few people understand it. Also, the DOD... you can't get a cam large enough to make much of a difference. There is no aftermarket DOD lifter that supports a lift higher than .550 or so.
