How much boost?

[ragman]

Any one know how much boost a stock 6.0 with stock bolts and HG can take without Blowing a HG or worse

I saw as high as 26 - 28 psi with stock tuning, my gaskets/bolts did not fail because of high boost pressures. If you're under stock programming still, you shouldn't have to worry about it, unless you find yourself under WOT frequently.

technically 28.6 psi is overboost. if your truck makes nearly that I wouldn't make a habit of staying there often

my truck makes 23-24 at most which i consider safe. The reality is you'll never know exactly when your headgaskets will go. just be smart about your driving
