Non responsive boost sometimes
Basically I notice often that if I am cruising (not in acceleration already) at like 3500-5000 rpms in 3rd or
4th gear and then go WOT, my boost climbs to 0-5 psi and rpms increase only. Little or no turbo response.
When I let off the accelerator I hear the "whooo" sound.
It doesn't do this all the time, but I notice it on the highway. It seems like my car needs to be running a bit
before it starts doing it but once it starts it does it
conistently every time.
I've taken it to 2 Rx-7 specialists and neither have been able to figure out the issue.
Any ideas?

A few mod notes would help...
Power FC
Profec B
Stock turbos
Pettit IC "3"
I had this problem when my Profec B was not working
and had to control with the PFC. The 2nd guy I took
it too said he removed the PowerFC from the boost
control loop and set up the Profec B not as standard but as he would set up an Apexi controller....for what its worth.
Anyways I still have this issue.
