I just installed a Greddy profce B spec 2 EBC in my car and i am having some issues with it. No matter what i do i get surging.
Firstly i know the unit works properly as i just removed it from my 300zx.
Secondly i know how to tune the unit (used it for the past 4yrs).
I have triple checked all my connections and done a leak test.
I have double checked all the electrical connections.
The stock solenoid is capped (both ports) as well as the nipple on the intake.
The greddy unit is connected using the `Com` and `NO` ports and NC is open
The Greddy line are connected to the compressor housing and actuator as per the directions with the second actuator nipple capped.
The boost signal for the unit is spliced into the brake booster line. (I have also tried the BPV line with the same result).
Is there something i am missing here? Or that I am doing incorrectly?
I have heard a lot of different suggestions about getting a bung installed on the intercooler, or an ATP silicone boost tap. Use this line or don`t use that one.
I`m looking for someone that has this unit installed and working in their car that would be willing to snap a few quick pics so that i can verify my setup. In the end I`m going to do a full write up on the full installation and tuning of the profec b 2 unit. I had absolutely zero problems with this unit on my 300zx and I`m a little taken back at how difficult it has been on my MS3.
Thank you for any help in advance.
