Bought some subframe connectors for the Duster from mancini the square steel bolt in type. I was just going to weld them in as opposed to bolt them in but I thought I read somewhere that people were doing both. I dont see the point in wasting the time drilling holes and running bolts if I'm welding them in or am I wrong on this?

We bolted first, then welded.
I was going to remove the bolts then gave it some thought.
I can see where it could be argued that the bolts give some additional
torsional rigidity.

i was thinking that also but wouldnt welding where the screw holes are would serve the same purpose?

Instead of drilling the holes to bolt them on, use the holes to plug weld. I think I like that idea better.

What is the thickness of your connectors? welding two pces of metal with vastly different thicknesses isn't easy and you often get a poor weld. Seeing as how you are probably welding 10ga (.1345) tubing or thicker to 14 (.0747) or 16ga (.0598), I'd go with the bolts myself...probably a reason they sell them as "bolt in".

Can't imagine when leaving out a strong piece of an assembly will make it better??

The most important part is to weld the perimeter to spread the load on the fairly thin frame rails. It can't hurt to put the bolt in also... that's what I'd do.
