I ran 11 lbs on my stock bolts on my a6 for 1 year befor I did a 4th gear pull and it let loose. I thew a mls gasket in and some arps, and never looked back. Best investmant you can do for a boosted setup. Like stated before, I have done the pull 1 bolt at a time and replace it with a arp stud and torque it down. And then the next one, and next one and so on. 6 months later and that h22 hasent had any problems and it gets run at 9 lbs everyday.

 

I would run them. Prety much just cheap insurance for not getting stranded or having to do more work later.
