I measured that the wastegate cracked open at 14 psi without adjusting the OEM wastegate actuator. With the actuator clevis adjusted in 3.5 turns, the wastegate opened around 16 psi.

I just installed my Forge actuator, and I have my ebc turned all the way down and my boost is spiking to 28 psi and holding at 26-27 psi. Is this normal?

If your you have your EBC tuned down and its spiking at 28lbs then your pre-load is set too high . Also did you install the lines to the EBC's actuator box set-up for internal wastegate ? Who tuned your car ?

Well the only thing I did was install actuator then turned my ebc all the way down. After I saw it spike to 28 psi, I adjusted the rod out and now its spikes to 22 psi, but drops off to 16-17 psi like the stock one did. Is there a sweet spot on it?

^I have the gizzmo msbc. My boost controller works fine, I don't really know how to explain how it hooks up. I just turned the boost controller down just to see what the wastegate would hold on its own. I figured if it would spike to 22 psi, it would hold 22 psi to redline. Right now if I use the boost controller and adjust the duty cycle it can hold 24 psi, dropping 1-3 psi. Just wondering how you guys made it hold 30 psi till red line? Thanks.

OK , so you start off with the EBC tuned down thus running off the per-load of the wastegate and that goes to lets say 22lbs . So what you're saying is that the EBC is not able to bring up the boost to ?? We actually spiked about 34 and held 30 with the same unit . You should not have any issues getting your boost set . How many times has your car gone into limp mode , just wondering .

Never. Weird huh, nor boost cut? Well I can set the boost, I just thought the actuator would kill the taper at like 24 psi. Will adjusting the pre-load fix this?
