3rd time is the charm? Stock bottom 2010 Camaro SS 76mm results Went back with new wires... they seem to hold, but I was having some boost drop issues past peak torque. After some research online, it may be tied to the boost controller.
Any who... here are the results:
8psi - 571rwhp/575rwtq
10psi (10psi @pk tq/9psi @ pk power) - 611rwhp/613rwtq
16psi (16psi @pk tq/ 13psi @ pk power) - 703rwhp/762rwtq
IFrom my research, iof it is boost controller related (the boost drop), it would be related to the "wastegate crack psi" I unputed. If so, it seems that the higher psi is a spike, and the psi it settles too is what it should hold flat (meaning, the duty cycle I had for 16psi really is for 13psi, but I saw a spike up to 16psi).
So... that would mean 13psi is good for ~700rwhp, but the torq at 13psi will be lower once I can hold steady boost.
List of mods:
Huron single turbo kit with Precision 7675
3" DP into dual 2.5" Borla ATAK
Stock short block (c hair higher than stock compression)
AI LS3 280cc heads
Vengeance Racing 235/231 .6xx/.6xx 115lsa
ported ls3 intake
NW 102 TB
93 octane - 1000cc injectors, stock fuel rails and lines, zl1pump, adm fpcm
slp underdrive 25%
Alky control dual nozzle kit...4psi turn on
AEM truboost and failsafe

Thanks!
I removed the filter (running a screen now), and that has seemed to help reduce the boost fall off in 2nd gear on street pulls (but we'll see if it helps 4th gear pulls on the dyno). I have twin 3" electric cutouts coming, so I will install those and hopefully hit the dyno one final time this season to see if it will make power over 6000rpm.
