The effect of camshaft changes on vanos timing

Let me start out by saying that I know enough about tuning old jeep 3.8 V6 pcms with hptuners to be a danger to myself and my engine. That is not much but I understand tuning concepts at least.

So to the question I have a low milage M52tu which has had an M54 3.0 intake manifold fitted for a while and yesterday finally the M54 intake camshaft was fitted. This cam has a little more lift and quite a bit more duration. Its still running the tune I had done for the intake manifold.

As double vanos is continuously variable I would think that the new can profile would throw off the DME calculations?

Does anyone have knowledge in this area?

Thanks.
