Running a CT9 hybrid with supporting mods.its all been mapped,no leaks anywhere as far as I know and only thing left to do is electronic boost controller, as for spool up it's painfully slow, starts spooling about 2.8 - 3.4 k revs and hits full boost at about 4.7 - 5.0 k revs at about 16 - 18 psi roughly. There is no actuator as I have an external waste gate which the diaphragm is fine and the correct springs are in,anybody else had this problem?
