Are you sure you used the right stretch numbers?

It seems awfully weird that the stretch wouldn't be right at their recommended torque... Do you use their assembly lube? Did you torque a couple times to "break in" the threads?

All of these things could result in requireing higher torque numbers...

I also noticed that on my ARP rod bolts the torque number on the sheet was much higher than they recommended for actual porsche installation. My stretch measured less than they recommended, but I was using a caliper,not a stretch guage and just did it for edgamucation.
