im running 13 psi on my 5.3, daily driver. no problems. dont see any reason why you couldnt turn it up to 16-17 for a reliable setup. granted i have studs, head gaskets, lifters, springs

i'm running minimum 16lbs on mine thats completely stock other than ls9 gasket's, studs, and pac 1218 springs. i usually am at 18 lbs (reasons why i want a better boost controller) but i have been up to 24ish pounds a few times on a spike and usually around 22lbs more than plenty occasions. and this is a 4.8 that i will do pull after pull on. I have all the faith's in the world in this motor. (good thing i parked it for a while now so i cant go blow it up)
besides the point your motor can take it as is, but to be safe you are good not going over 15.
And what was your exhaust before and what is it now to make that much of a difference?
