external wastegate not opening

[T9S1i]

? another question, does anyone know if theres a difference between a stock 14b internal wastegate to a stock 16g internal wastegate or are they the same?

14b housing is a 6cm housing, spools faster, less flow up top
16g housing is 7cm housing, spools slightly slower, more flow up top
Wastegates should be the same size.

Make sure you arent running an exhaust manifold with a 7cm collector and a 6cm turbine inlet, it wont line up right and might blow a gasket.

i dont know where this threads going but with the external wastegate where the internal rod went into was welded shut also, who on here has ran with a hallman mbc and had problems with it becasue i think thats the reason why its going up to 10psi and holds steady untill around 5 grand then it goes up to 15 psi where the bc is set at and holds steady all the way till redline and yes the bc is hooked up rite and on in the rite direction .
