The 3200 gov should give you a higher boost number. Becuase you are more available fuel at a higher rpm equals more exhaust velocity through the turbo.
A timing jump however will decrease your boost a little, even though an 1/8th might not be enough to change it. Reason is you are holding more heat in the cylinders which doesn't spool the turbo as much.

There's also a chance you'll end up on one of those dynos that will give you a 300+ number, but I wouldn't put too much heart into it. My truck, with a stick and an S362 did 268 horse. Stock injectors, fuel pin, LPLP, and 4" exhaust.
Do you have an upgraded LP?
