Boosting only 7psi max, thinking tvsv is the culprit? Options

[malecrod]

Hi,
I have a boosting problem. I'm only boosting 7psi max. This all started with a leaking turbo to downpipe gasket ( looks like ebay type) that was making the car loud. So I took it out and replaced it with one I made DIY as a temporary one since the toyota one I ordered was taking a while to get.
Since the replacement I'm unable to boost more than 7psi max. Ok so I read a lot the last few days and thought: boost leak,gasket/ebay downpipe is making wastegate flapper stuck. Checked clamps, hoses no leaks anywhere. Finally, the toyota gasket came in, but before I installed it, I ground it down to match the OEM gasket(don't wanna have any reason for taking it down again). Installed everything back, but still can't boost past 7psi.
So next I unplugged the hose going to the tvsv and run the car, got it to 11psi and I could hear the turbo working hard so I didn't want to push it to overboost. I did not feel the car pulling timing on me.
Next, I plugged the wastegate actuator outlet to tvsv shut, went for a drive, all I got was 7psi! which is what it should be.
Now I'm suspecting either ECU is stuck in low boost mode or the TVSV is bad or could this still be boost leak?
I have the boost leak tester in the works.
I have checked my BPV for leaks and even took it out of the picture for simplicity sake still no luck.
I need all the help/input I can get.
Thanks.

the problem was that one of the silicone connectors would pull apart a little while i boosted and cause a leak. this was a very sneaky thing considering that i checked them and they were all tight. i ran a boost leak application and found the problem.

thanks,

You should change all of those clamps to T-bolts. Those worm clamps that are on there now will give you nothing but problems. I use you have piping blowing off all the time, even while driving. But with t-bolts, I haven't had a single leak in 4yrs.
