1100 for a peak is no biggie...
If these things blew up at anything past 12 psi or over 1200 indicated, my truck would have been dead 2 years ago. I can easily push 15 psi with an empty truck(I cruise at 65-70 with a 300-350 egt, and can't get past 950 egt with no trailer no matter how hard I try, but, I run out of smoke at about 12 psi, I should turn the pump up more) and, with 14,500 in tow, I run a maintained 10 psi/1200 egt for 5 miles on one stretch, and this happens every time, it actually starts to cool the egt's down once it builds enough rpm to get the boost up past 12 and cleans up the smoke(I really need a smaller exhaust housing on the turbo.)
I don't exactly baby my 'ol girl, I only back off the throttle for overheating, and that usually happens long before I need to worry about EGT's, even on long hard pulls with GCWR's in the 18K + range(old fan clutch never locked up.)
I have factory head gaskets and bolts with 170K miles on 'em... Everything I've ever read on the internet says I should have cooked pistons and popped head gaskets long ago, but it still lives.

. Last week it got down to -7 at night and it started up within 2 seconds and not pluged in. With the new glow plugs and the blue top optima batteries it starts like it's 80 when it's really 0.
