Are you having the boost oscillations at stock boost? Does it just spike or does it go up/down constantly WOT 4th gear?

I'm not sure if a GM BCS will fix that. If it's doing it with stock stuff you might have other problems like stock stuff failing.

If you are using the gm 3 port you no longer need to use the restrictor pill.

hey guys, i just installed the solenoid but i couldn't hear it clicking at all. The car at idle would show 20 psi vacuum and it'll boost normally i hooked up the access port and the wg at idle was 0 and was going up and down in percentage depending on throttle the other # besides the percentage was showing for example 0/16, and it went up as i drove 0/20, 0/40. I connected the wires B- black A- yellow
Is this all normal and how can i find out if the solenoid is working or not. Please someone answer me asap because i don't want to drive the car before i'm sure that everything is ok.

You cannot see anything in the logger that would directly tell you that new solenoid is working or not is some generic fashion. It has to be tuned. The WGDC you see in the logger the ECU is driving the solenoid, not something coming from the solenoid. You can only log boost and WGDC which is a tuned relationship, not something you can roughly tell working/not working condition. The only thing that might happen is you get a CEL if there is a big electrical problem with the solenoid. Other than that if you double checked your setup, you have to start tuning it and see if you get more than wastegate boost. Start low, general/rough tuning advice already posted, or find someone competent to do it for you.

If you mount it right on the metal bracket and use no rubber grommets it will make it considerably louder. You can also try touching the wires directly to the battery + and - and see if it clicks. I already posted about testing it this way in the first post. You can touch it to the battery and try to blow through it. Where you can blow in and where it comes out will change when it has 12v applied vs. disconnected.

I connected it to the battery and it was clicking loud and clear. When it was disconnected the air could travel from wg pipe to turbo and the other way around but when it was connected it was getting blocked. I asked my tuner for a map to use until friday when i'll get protuned and the tuner is 100 miles from me.

^^Just in case you do not get the map in time, just keep an eye on your boost gauge and drive around carefully. You do not want to overboost at any time. Given the stock map, boost targets are hit and exceeded pretty easily with the upgraded solenoid, so you wanna keep an eye out for that.

On a slightly off-topic note, I first had Perrin's EBCS installed and tuned with Open Source reflash. When my motor spun its bearings a few months later, the Perrin decided to go south as well. Now I have the GM solenoid in its place, and I can tell you straight away that this unit seems to be much stronger than the Perrin. Boost target is easily hit and exceeded given the map for the Perrin unit. More tuning is in store.

My GM solenoid that I installed spring of 2007 is now making a really loud clicking sound between 1700 and 2500 rpm just during daily driving. Is it toast?

Check to make sure the solenoid isn't touching part of the chaise. Mine shifted at one point and was slightly touching the strut tower and you could hear it clicking away in the same rpm range, twisted it and tightened the bolt, no more audible clicking in the car.
