Pulls to right

Hey guys, I need some help here.

I recently had a front tire snap a belt on my Duster and took it in to the shop my brother works at to get a pair of used tires swapped on and get the alignment done, since it's been chewing up tires as well. It is a street/strip car with 90/10 shocks and /6 bars in the front.

They had the car over several days time, partly because of the drag shocks and alignment changing when the front is at down-track height. I accepted their latest try with the understanding that I can bring it back if I decide to and they'll take another shot at it.

It currently has a fairly strong pull to the right while cruising down the road but is almost completely gone when under power. I thought it might be a radial pull, so I swapped the front tires side-to-side, but it made no difference.

Here are the alignment specs from the sheet they had printed off:

Left Right
Camber: -0.4 -0.3 degrees
Caster: 4.6 4.9 degrees
Total Toe: 0.20 degrees
At 2+ inches suspension rise, the toe is at 0.70 degrees.

I was thinking that the extra caster on the right side was probably the cause of the pull, but I wanted to get some input on the current settings before I have them jack with it again.

Thanks.
