Hi everyone.

I have a rx7 with the following mods.

non-seq. turbo set up
Intake/DP/MP/Cat back
Efni Y-pipe/crossover tube
FMIC
Apexi PFC
Blitz Dual Spec s Boost controller


Problem:

I am getting 7lbs boost regardless of boost controller setting.
with boost controller in off position.... .50 HKPA ~ 7.25lbs of boost. (through out RPM range)
I change the boost controller to 80% and I get .55 HKPA ~ 7.9lbs boost. (through out RPM range)

What I have already done.
- Checked all vacuum nipples (changed anything suspicious).
- Checked vacuum lines (all look good to me).
- Replaced primary and secondary fuel injectors seals/o-rings (had a gas smell, fixed problem)
- Changed out the FPD (although not boost related)
- Changed LIM to UIM, UIM to TB, TB to Elbow gaskets (they looked bad and did leak)
- Changed O-ring between Y pipe, gaskets from turbo to y-pipe, and from Y-pipe to crossover tube (all new gaskets were used).


I can't here any boost leaks per se.....so I am confused. I am now looking at how things are connected and am wondering if something is installed incorrectly. Mind you, I bought this car with boost leaks in it.......I am redoing the car and would like to get it back to 100%......problem is....I don't know how the car is supposed to look like in the non-seq. set up...and most troubleshooting online is for the sequential set up. So I have a rats nest of unused electrical connectors under my UIM and I can't say I know which connectors go to what exactly. so I am unsure if the electrical connectors I am using are hooked up correctly? I did not perform the non-seq turbo set up....It came that way.

I have looked at the vacuum diagrams....and mine is set up like that...except I have a couple of questions about my set up that is different than the diagram. Video below.

I also plugged (vacuum nipple) the vac line to the boost controller primary turbo and wastegate....did some runs and I still get 7PSI boost with a plugged wastegate actuator. (I don't think the boost controller solenoid nor the wastegate is the problem).


From the video, is this set up correctly? What controls boost from an electrical connector stand point? I am just trying to ensure all electrical connectors are installed correctly....and all vacuum lines are installed correctly.

I have done some boost leak testing (pressurize system) and found some leaks in the UIM area....and those are the gaskets I have replaced.....but I have yet to test again a second time.

 

it could be the boost controller, I also have the Blitz Dual Spec s Boost controller and although i had it connected correctly is did not work.. I ended up getting a hallman manual controller and it work flawlessly every time.. Get rid of the Blitz Dual Spec s Boost controller there is a problem with the solenoid

 

I put a vacuum nipple over the primary turbo input to the boost controller...and I also put a nipple on the wastegate vacuum nipple......this essentially took away the boost controller. I just used the boost controller for monitoring the boost level.

I still was at 7lbs boost.....thats with no wastegate at all.
