2nd turbo not kicking in.

Hi guys,

Having a problem here.
Give it a boot full, but doesn't seem to be any 2nd turbo. Maximum boot is about 7 PSI. Has an Ecutek program from a previous owner.
Still getting a Vod and I'm pretty sure it is spooling up, but I think whatever opens to get the 2nd turbo to start injecting air into the intercooler is not happening.

Any ideas for an easy fix?

intercooler control valve aint opening or the secondary bov is cactus or the exhaust gas control valve aint opening or the differential pressure sensor is rooted.
