boost on gauge/profec vs PFC

i just installed my power FC and drove around tonight
i was tuned by SR for my mods as well as IC and midpipe since IC is coming soon and midpipe will also be as well.

before i had g-force unlimited ECU and controlled boost via a profec B. (turned off -6.5-7, low: 9.5, high: 12.5-13)

after install i checked the sensors/sw page and noticed O2 sensor was not getting any voltage. i decided to take it easy b/c of this. however, i figure the car was tuned to produce fuel as an aspect of RPM and boost pressure and not O2 sensor voltages. i will replace it regardless.

i did a few runs with the profec turned off and then also with it on low boost as well as just normal driving around town.

peak values:
i feel like my intake temps are WAY too high at 87*C
water temps are good
injector duty at 9.5# is 69.5%
i havent monitored ignition timing live in detail yet

what im having trouble with and questions about is that my boost gauge reads 9.5psi while the PFC says im producing .46 which equals out to 6.53

this number worries me since the profec when turned off reads the same. maybe how the profec is hooked up is screwing things up?? it was installed by RP while i was at school and unable to do it myself. point is, i know its hooked up right.

am i getting the 6.5# b/c the pills are not present? im going to look more in depth at the profec install/routing tomorrow.

any feedback/suggestions??

call if you know exactly whats wrong or have a pretty damn good idea 214-673-7720
if youre not sure then discuss it on here and see what y'all can come up with. id like to get things figured out and working correctly by tomorrow night.

thanks for the help

OH.....and should i be seeing any knock numbers at all??
