You could reverse the 2 lines going to the wastegate so that the top of the gate always sees boost pressure and the bottom is controlled. You'll have to reverse your duty cycle.
Then the gate will be held closed by the turbo. Using the boost controller to allow full flow to the bottom will mean you'll basically be relying on back pressure to force the gate open. With a 3.8 lb spring that won't be an issue.
It'll take some time to dial it in.

I think the best bet is going to be installing a small blue 8.7 lb. or large yellow 10.1 lb. base spring and that way I'm covered for 13 lbs. now and 18 lbs. for the future.
Thoughts?
While I wondered about doing something like that I can also see that going really wrong lol.

This unit has both a boost cut and AFR cut feature, I'm not seeing a 5v output on the schematic.
Good news gents,
I went ahead and installed a 10 lb. spring as well as pulling the wastegate apart, giving it a good cleaning and lapping the valve/valve seat since it was quite dirty.
The performance is now where it should be and has exceeded my expectations I must say.
The car now comes into boost much harder so that the MT ET Street R's are struggling for traction and leaves black marks on my favorite on ramp from a 40 roll in 2nd gear.
As always thank you to everyone who chimed in as your wisdom is always appreciated.
Have a safe and happy 4th of July!!!

I'm looking to run right around 13 lbs. same as when I was on gate, I was really just looking to gain the advantages of an EBC and not make more boost since I'm already at the max boost the tune will accommodate.
A good friend of mine ran a TT LS setup with this controller and a 4 lb. spring making max boost at 22 lbs. without issue.
I realize every application is different and it sounds like my back pressure is opening the wastegate prematurely, slowing spool until boost pressure can over come the difference.
I guess I just assumed that in order for the boost/afr cut to be effective it had to dump as much boost as possible but that may not be possible with my setup and such a light wastegate spring.

I have a cortex, run a 4-5lb spring and i can dial down to 3psi in 1st gear and 10-11 in second and 13 in 3rd. 3 port solenoid is what i'm using. I will say that when I installed the ebc, the boost comes in more controlled and doesnt blow the tires off at 40-60mph anymore. was cool to do sometimes but not safe.
I'm pretty certain my setup generates too much exhaust back pressure to run a spring that light.
I don't mind blowing the tires off, just means I have to drive the car a little more with street tires.

Sorry to bump an old thread, but it's hard to find people running the SCG-1.. I have the 6 lb spring in my gate and I normally set the duty cycle so it sees about 16 psi, with boost cut at 17.4. The problem I have with this controller is that it seems to be laggy building boost and has just murdered the transient response when shifting gears. I used to have a Grimmspeed manual controller and it was so much better getting back into boost when slamming a gear. Watching the gauge, it seems like it wants to wait a second before activating the solenoid (you can see the % cycle it's at as soon as it activates). I've tried setting the activation pressure down to as low as 2 psi (the manual says about 2 psi below spring pressure is a good starting point) but it doesn't seem to matter much. I'm wondering if putting in maybe 9-12 lbs of spring pressure in the gate would help this, or is the controller just going to always be slow when it comes to shifting and transient response?

I tried a 3 lb. and a 6 lb. spring individually but both made the combo spool slowly, installation of the 10 lb. spring immediately fixed it.
I checked everything in between as well and the heavier spring is what fixed it.
The combo became noticeably more violent coming into boost with the EBC though, it hit hard and annihilated the tires to the point the new owner totaled the car after owning it for less than a month lol.
You could always explore compressed air on the dome as an option if you really want to have complete flexibility?
