i think i found the limit of pump gas, bumped it up to 11.5psi and got some knock, i was seeing about 15deg of timing, cut it back to 10.5 and got no knock, going to stick with 10.5psi for now.

at 10.5 psi i saw another 60lb/min of air and my gtech run was a 12.92 at 115 with a 2.32 60'

at first i was saying to myself that this thing is fast and i may not need a 409, well.... i am geting used to it all ready and can't afford race gas all the time so maybe i do need a 409 with a cut out and 4wd i could see some very low 12's or maybe a high 11 on pump gas on a good day, then some race gas and see what it will do. 10 more days to some track time.
