Horrible
44mm wastegate had all the set screws come out inside the unit from day one which made boost control impossible. The diaphragm would not seal which also made the boost impossible to control. The spring that come with mine was supposed to be 14psi and they in fact appear to be 7-9psi only which will not allow me to meet my boast goal without finding different springs which seems to be impossible also. Save your money..... or DNA Motoring ..... prove me wrong
