Wideband readings dangerous???

I ran my car under full load and WOT for the 1st time last night. I've been breaking in the motor.

Stock boost
FCD
3" turbo-back exhaust
monster street port
stock injectors
255 Walbro


I hooked up my friend's AEM wideband and boost gauge and went for a spin...

1st gear pull WOT: read about 7 PSI and widebead showed 11.2 - 11.5
2nd gear pull WOT: boost read about 8 PSI and wideband jumped from 10 to 13.5 instantly. My friend said NO GOOD...

I wanna know waht the readings on the wideband display are indicating. Am I leaning out under boost?

I have a SAFC not yet installed cause I'm looking to buy my own wideband to tune off of...

probably a lean spot when the secondary injectors come online, this is not uncommon. Make sure your grounds are clean and consider upgrading to 720 secondarys (if you want to turn up the boost later) with the Rtek 1.7 chip which has better injector staging.
