Need GReddy Profec B Spec-II help

Hmmmmmm, I don't actually have the stock GReddy intercooler, I have the Godspeed (eBay) intercooler. It's definitely possible thats having a larger effect. The turbo outlet probably has a screw blocking that port because I found the copper fitting in the picture someone posted in a box this morning.

The Greddy intercooler starts to become a restriction to flow at around 220g/s which is only about 5000rpm at 9spi . By the time you reach 320g/s (roughly 300whp)you have a pressure differential across the intercooler of around 4psi .
If running the stock Greddy turbo this intercooler is fine but anything bigger than that making over 300whp would benefit from a larger intercooler.
I have run mine up to 350g/s (333whp) and saw a pressure differential of 7psi .

Here are a couple of pictures of the valve and the lines:
Here is the empty NC port:
Attachment 147310
Here is the red line to the wastegate actuator connected to the COM port: (to make this line reach I had to turn the valve box around as the red line is very short)
Attachment 147311
A top down view of the valve unit:
Attachment 147312
The blow off valve line running back to the VFAD, with the other blue line coming from the NO port of the EBC solenoid valve:

Now that the w/g is working, I started tuning my boost controller without fear of the engine spontaneously exploding. With the start boost tweaked and moderate set values I get almost instant boost to 9 PSI by under 4k rpms. Once I get a new map from Jeff I will continue making adjustments to raise the boost to my target, and keep it until redline.

Did you replace your transmission already? You upped your boost again from 14 lbs??

Yeah, I tweaked it a bit more and boost comes on to 9ish PSI by 3500 rpms now, but I'm holding off on raising the boost until I get an updated tune from Jeff and I get my fuel pump installed. My target is 11 PSI.

Hey guys i need a small sugestion here!
as my car is a 4 port it does not have a VFAD,so i managed to make a vacuum fitting for the pressure source to the solenoid in one pipe pre intercooler like the profec manual says,but where should i put my MAP sensor from the emanage,the boost controler's input and my boost gauge as the only vacuums i have left are on the LIM?
Should i put them there??i will be greatfull for any advice!!!

I can't believe you are forging ahead with your plans after the advice you have been given on this forum already .

You're missing The Kiwi's point. Please re-read the thread again. OR read Kane's Boost controller "How-To" thread.
Knowledge is power.
Yeah, post 2000, of course in a old threadsurection, to boot. I fail.
