tial bov

does anyone have a tial bov that is running more than 18 pounds of boost?
the only spec sheet i have every seen quoted that the tial bov can only withstand 7-15 pounds of boost. is this true and if so are there different models of the bov? i am going to be running about 22psi on the track and about 4psi on the road so if i could encompass these boost settings with the tial that would be awesome otherwise i will have to look at other options. thanx in advance.

I've never run more than 18 psi (on purpose), but my BOV has always cracked when it was supposed to. I have the rotary spring.

I have a tial and tuned it out for 16psi, On a later tune up though it was running 20 just fine.
