How much boost are you running with factory headbolts/gasket

[Jason]

Hi folks,
just wanting to get some imput on what kind of boost levels you are running with stock headbolts. Is there anyone out there that has installed a set of ARP studs? I know this is a popular mod on the 1.6 vw diesels (which I have had) and they run pretty good boost 15+lbs with thet stock gasket. You can upgrade the head gasket to the metal TDI one for the 1.6, is there a better gasket than stock for the D24T?

I'm thinking 15lbs with an intercooler and bigger exhaust... Too much?

Thanks,
Jason
