I have no idea, haven't had a chance to get it to the track yet. However, with a passenger and my car weighing 3870lbs at the time, it broke the tires loose at over 100mph on a set of 315/60's and 3.42 gears.
FWIW. It only spiked to 30 but then holds 25lbs. Here is a video of me and my buddy who thought I was full of ****, so I had him video the boost guage.

What I really want to know is how well they are holding with factory heads like 317, or 243's. I ran 20~22 psi on my normal MLS GM truck gaskets a few times with no problem but was afraid to go past that. The LS9 gasket has 4 embossed O rings in it's layers where the older truck gasket has 2. That being the case it should be able to flex/ lift more before it looses seal.
btw 26psi with no probloms at all
