Yes, please re tighten them after a couple thermal cycles. Its the thermal cycles that cause the metal to expand and stretch the bolts.
Its the same reason why Nissan puts their demon cat bolts on so tight in the first place. The stock bolts are literally stretched at the factory by super torquing them... and that is why they never come loose.
They are using a big impact wrench on the stock bolts and they really crank it down.
On the order of wheel lugnut tight.
