1st gear boost
 
i've noticed that tonite my car is only boosting around 6-7 psi and struggles with that but when i shift to 2nd gear and all the others it has a perfect 10-8-10 pattern. is it just me or is something wrong?? Is that normal or do i have a vacuum leak somewhere? how

a vacuum leak would affect more than just 1st gear...so im not sure..

boost is load dependant... you will never get the same boost in 1st gear as you would in say 4th.

especially when first just spins :(

you still should be hitting 10 psi in first. ican rev my engine and get about 6 psi.

Check for a small boost leak somewhere. its possible that a small enough boost leak will show its face in first and not other gears since they are geared longer and the turbos have time to compinsate.
