Are you doing re-torque after a few heat cycles? What are you are you bringing your studs to? 125ftlbs? Letting the truck warm up before boosting it?

I would say you have a straightness issue or the sequence in which your tightning the studs is incorrect. Are you using moly lube on the studs and washers before torque?
