Wastegate Setup For R32 Gtr... I Need Help

[MAD R32 GTR !]

Hey guys... Just having a few problems with my boost control at the moment. All of a sudden it over boosted up to 30PSI. Now it runs unlimited boost. I pulled off my waste gate and everything is running smoothly. No broken spring or valve. Its only 4 weeks old.

I've clamped the vac line that goes to the top of the waste gate and it regulates the boost now

I don't get why you need 2 vac lines going to the waste gate?? Don't they fight against each other

Should i pick up my vacuum from somewhere else other than idle bypass valve? Should i run just a boost tap style setup

Below is a picture i drew up of my external waste gate setup. Running a t04z

Any advice would be helpful. Thanks guys

I wouldnt take the boost signal from where you are, id drill, tap and screw in a hose barb to your intercooler pipe just after the turbo, use new hose, run straight from the cooler pipe to the bottom of the gate. Unplug the top. That way you eliminate any chance of cracked pipes or hoses, and boost spikes.

If it still overboosts then theres a prob with your gate.

If it runs reasonable boost (whatever spring you have in the gate), then T off that line for your solonoid, similar to how it is now for the top part of the gate.
