Built a boost leak tester today, decided to just remove the MAF and hook it up there instead of onto the turbo (I told myself it was for thoroughness, not laziness). Glad I did, the HKS BOV (recirculated) was leaking like a sieve. Replaced it with the stock BOV and there were no more leaks.
So in summary, House M.D. was right, it was not a compound failure, it was a compound fix. Because it didn't build boost with both BOV's at first. So, I believe that somehow, one of my stock Wastegate Solenoids went bad, and I switched to the 3-port AND the HKS at the same time, and missed an error.
I really should start diagnosing and fixing problems one variable at a time.
Thanks for all the help guys!

Didn't have a easy way to put 11psi to the wastegate line tonight. Decided to up the WGDC in 5% increments, upped it from 50%-70%, only in the 79%+ throttle area. The result was 13psi. Which doesn't seem right.
Going to hook the wastegate up to my compressor in the morning, and go to Lowes and build a boost leak tester

Take the line off the waste gate, apply 11psi to it and you should see the rod start to move. Either with regulated air or with a mivac pump thingy to test it.
unless its partially stuck open. Then that would be the suck. But can remove the pin and move the waste gate arm freely.

I'm killing two birds with one stone. I contacted Chet and started my tuning process. Installed the 3-port and got a map that is supposed to make it work. I am fairly confident I installed it correctly, I even had a friend read the instructions and check over my install. put Chet's first map on the car, idled well, drove around town at part throttle well, decided to try and build boost, wouldn't build past 10.
WGDC is currently set to ~50% and should be building to 16ish psi.
Could my wastegate be borked?

|surensm||Do you have a tactrix cable? You didn't specify how you read boost, whether it was through the gauge or using evoscan/cobbap. You could just put your 3 port on and decrease your WGDC values by 35 percent. It would be much safer that way.|

|chetrickerman||If you do install the 3 port, be extremely careful going into boost because it will not limit the boost at all|

|achinaghost52||Took off the wastegate solenoids and sprayed the connectors and contact patches with QD Electronic Cleaner, still no change. I have a 3-port, thinking of just installing it and being very careful with my right foot to see if I can get it to build past wastegate spring pressure.|

I did not get tune. I am about to, but obviously I need to figure out this issue first. I did switch the lines on the solenoid (the ones coming from the intake and the wastegate) and boost was the same, although idle was rough, so I switched them right back.
How do I check to see if the solenoids are working correctly?

|surensm||I remember you had a thread where you asked if you should get tuned or not. Did you?|

|ripnet||Sounds like you are running wastegate spring pressure. Check your solenoids. Do you have a 3-port or stock?|
