I have not found anything that matched my case. Basically I got perfect 10lbs boost on primary, 8lb transition. secondary goes to ***, sometimes will hold 5psi and creep to 8psi, by 6.5-7k 2lbs at best, redline 0psi. When I let off above like 6.5k it makes this real weird boooweel noise *best way I can describe the noise* I have checked all of the vac lines without taking off UIM but I am able to see the control solenoid and all lines seem to be on, CRV is not venting ANY air anymore, I checked all hoses, everything seems to be fine from what I can see. I tested out a extra solenoid i had in my bench from previous rx7 when I went single, but wasnt the exact same solenoid so I dunno if it would have worked anyways.. Anyways no dice on that either. I really do not want to do non-seq, the seq is so smooth and great for spirited cruising. If anyone has any ideas please let me know, I have not took the uim off yet because I dont feel like disconnecting those annoying *** tb coolant lines, and all that crap. If there is something under there I cant see with it on I guess I will take it off. Thanks in advance!

Have you checked the other simple things? Like leaking oil, checking all the manifold and turbo bolts, etc? Do you have a PFC to monitor voltages?

 

The "Coooweeel" Noise is probably your emmisions air pump... It makes a cow noise... Kinda anoying... hehehhe.
I would try a profec B~~ That has solved my problems... I was getting boost creep all the time and tried the manual boost controller and it was complete ****!!!
For the boost controllers you get what you pay for... so get a profec B try it out and if its not the answer then return it~~ easy~~

 

crossover pipe might have a crack, it is hard to notice

 

airpump is removed. My CRV is not working at all, the valve is good however. There is vacuum on the line at idle and such. Im kinda thinking it might be the vacuum lines under the car going to precontrol and wastegate

 

did you recently remove the uim and reconnect the connectors in the front backwards. I'm guilty of this and if gave me crap boost.

 

I would check a couple things:
1) clogged cat
2) run a KOKO test and see if your secondary valves are closing (the Turbo Control and Charge Control). www.fd3s.net/boost_test.html

 

I am not running any cats, havnt taken UIM off yet, but I am gonna check those lines under the car and do the koko test as dgees has recommended. Thanks guys for input.
