yea how do you create a boost controller for something thats spooling 10psi..

if i pinch the line i can get it to boost more psi, but how do i make the wastegate sense under 10psi? would a thinner hose create more pressure and in return push more air to the wastegate so it opens sooner?

check your flap for bending and cheafing ,and check your wg hose for leaks.

i just replaced/re-tightened the wg hose.. still boosing 10, however the shaft that runs the wg seems a little bit crooked, i must have bent it when i re-installed it... could that cause it to ---- with boost?

It must be the rod (shaft as you call it) the boys around here use to bend it to get more boost so try straten it a bet that could help.
