Question ~NEED HELP~ what WG with a gt-91 turbo?

i have a TIAL 44mm already...

my set up is:

2001 Full size regular cab truck (4200ish lbs)
GT-91mm turbo (1.10 a/r)
408ci (9.25:1cr)
4l80
3.55 gears
KBracing Front mount setup
4" down pipe


my question is.. will the TIAL 44mm work i would like to be around 13-15psi (pump gas)
or will i need a bigger WG?? i just don't want to spend the money on a bigger one if this one will do what i need...

44mm is fine for the turbo size and boost level.

Yeah a Tial 44 will work or the Turbosmart 45mm. About the same price and its a killer gate as well.

all depends on the kit and gate spring. Also if the turbo is huge 91mm then trying to run 5psi out of it can be a problem.
