HELP: 1st gear + clutch + brake = stalling out

[muibubbles]

read a few of the stalling threads non had the symptoms i have...
here are my known symptoms, they may not all be related...

car takes a few seconds to crank before it catches- hot and cold starts
if im in neutral and slam the brakes car is still fine
if i clutch in and im in 1st gear and brake, the car stalls out
idles at 1000rpm (was having previous stalling issure so raised the idle)
vacuum on the commander reads ~ -36xmmgh at idle (i believe it should be near -47x mmgh car has a mild street port)
boost gauge reads around 12 vacuum ( i believe i pay more attention to the pfc)
volts are reading hight 13.x-14.1

any suggestions what could be the problem?
