Help with infill over support area

Attached pic is of the bottom of a part I'd like to print. The right is the part extruded on the build plate. On the left there is a small tab that that requires some support. I can't seem to get those areas that print above support to look that great. If I print a solid part from the plate up the layers all look good and solid but if I print over a support structure they look sparse as if I was extruding only a fraction of the material I should.
Any thoughts how to fix this? Maybe someone has run across this already.

That hard of an issue that nobody has any suggestion? I was thinking that maybe a higher density support structure could help but not sure. Also there is that empty layer between the support structure and the actual part... maybe eliminating that would help but then the support would be much harder to get off. Hm. Need to do more experimenting I guess. Maybe it's time to buy some HIPS

what are you current support settings?

I think that print was 50% support 1 empty layer. I'll have to double check but that seems what I used.

Well I'm solving this now by printing at about 60% support density and I changed the support separation upper layers to 0. The only way to do that and get reliable prints though is that I got some HIPS to print the support structures with. IF support and main plastic are the same I guess this is just a hard to deal with issue.
