I didn't touch the wastegate arm, and it started after I installed an up pipe, the turbo back was installed first
I'm getting a little worried about it
I'm going to try a smaller "T"

I've had the 3/16 and and uppipe, but never both at the same time. I got over the BS of the 3/16 mod too quickly.
Yes, the 3/16 mod can make you spike. I know with that and am MBC bleeding, I had hit 20psi when I had a td04.
As for an uppipe, this really don't make a difference for top end boost, but will help spool. What will make a difference in top end boost is how the exhaust opens. I've never heard of a TD04 having boost creep due to a lack of cats - but that doesn't mean can't happen... but then creep isn't spike.
Basically, there's not enough info to figure this out.
