Data Analysis Help Please

Car runs rough and wants to die when you put it in gear.
Zero boost under brake load.
Here's what I have, but don't know what it means.
Car is warmed up and in closed loop.
Thanks

IAC index 14# 5%
LV8 (Load) 37#
TPS .42
Integrator 120-132
O2 Volts 121-760
MAF 6GPS
Block Learn 146
RPM 850-900

High BLMs and high O2 voltages (the 760) makes me think cracked exhaust manifold.

Thanks for the reply.
Put in the old chip (for 009s even though I now have 50s)
BLMs went to 136
02s went to 160-734 at idle.
No more bog in gear and 4+lbs of boost with the brake pedal mashed.
Thanks again for the input. As my dad used to say "We're missing closer"
