I found a couple of threads that sort of mentioned this topic, but nothing definative. Does anyone have a straight forward answer? My TCA does not move with KOKO (I have PFC) but seems to be working fine at transition points based on vacuum/pressure gauge readings. The CCA does work fine with KOKO test. Thanks for helping to clarify this issue.

I have the same problem. CCA works but not the TCA on KOKO test.

I have issues building boost before secondary kicks in.
