I am interested in this also, what is the maximum boost that the headgaskets can handle on these engines? I know the EGT's setting is 1350 and the transmission is 210, but I am unsure of the maximum safe boost numbers, I have mine set to defuel at 38 PSI.

I have my defuels set at 1400 EGT's, 36psi boost (more worried about drive pressures than boost), 210 trans, 210 coolant hot, 130 coolant cold

I'm running H&S smaller tunes in my Black Maxx (0, 40hp, 80hp, 130hp), so EGT's aren't really a concern, but the boost will still get up there...

My defuels are very similar to rockinjw, except, cold coolant 160, max boost 38, and egts 1250. I am running the h&s mild tunes (80,150,225). I did take my defuels off the other night and ran the 225 hard for about three pulls. Max egt was 1650 and boost saw 46 psi. These bigger tunes from h&s definately push the truck hard so I would watch out if you guys are choosing to manually defuel your trucks..
I doubt I will ever run my truck that hard again but I wanted to see where the upper end of my hot file was.

Jacob, is there anyway to monitor engine back pressure on the black maxx?
Also I was seeing 34 psi boost stock, so I figured another four pounds would not be too big of an issue, what were you seeing stock boost wise?

I am also running the Mild tunes (0, 80, 150, 225) and I am using the 80hp setting. I have had it on 150 hp setting once and I have never used the 225 hp setting Please explain drive pressure? What are you refering to?

Back pressure is the pressure against the motor due to exhaust not being able to escape the turbo fast enough, or at least that is my understanding of it.

If it gets to high pressure in the cylinders will be great enough to stretch the head bolts and pop the head gaskets causing the infamous "puking" scenario. I don't think on the 225 file there is too much to worry about. Most head gasket issues I have read about have been on 275+ files.

So if I am running the 0hp tune (Just using to delete the DPF) I should be pretty safe using the stock defuels?
