keep it at stock boost levels until you can afford to stud it.

I have seen them hold 60 pounds but not for long. Your stock intercooler wont take much more than 40 or 50 pounds I dont think. Someone correct me if Im wrong

I think its a combination of heat, and boost.
I ran the Extreme Race everyday in my truck for over two years with no problems. Then as soon as I pulled a Duramax on a heavy car hauler trailer for two days straight...the heads cracked enough to leak coolant. And when pulled apart the gaskets were blown out between the cylinders.
Not saying it was just from the car hauler, but it helped I'm sure. (My own fault for not changing the tunes when needed, but I like the power of the Extreme Race tune.)

I had around 35 psi max boost on the stock 03 turbo with stock head bolts.
If your gonna run a tune, its only a matter of time before the motor will need studs...JMO

I have been hitting a max of 33-34 psi on my stock bolts with Matt's SRL tune. I would consider this tune to be an SRL+ tune though because I thought SRL was supposed to max at maybe 28psi. I have a an 03 turbo and an egr delete. The delete may have something to do with more boost but not sure.
