Oops on the main cap torque

I misread the torque spec for the main caps on the 318 we're building. I torqued them to 100 ft/lbs instead of 85.

Should I back off and re-torque? Or just let it be? Or get new main bolts and re-do? Hard to imagine that just 15 extra ft/lb would stretch the bolt too much, but I'll defer to those of you wiser than I.

Grateful for you wisdom, I am,
JD
