Angry up pipe leak

i just replaced my up pipe gaskets with some carquest brand ones and i still have a leak. i tightened the bolts down as hard as i could. is there a way to tighten them without pulling the turbo again and also is this why my boost is reading way lower than usual and drops instantly when i let out of it? thanks for any help

Did you use a new white seal when you did the carquest donuts?

If they leak, you did not tighten them enough. I have over 50psi of backpressure and there are no signs of leaks for the last 6 months. I have put these in a few trucks now without any problems.


They should be grey/silver. They are graphite. I have not seen the white ones before.
