Bog issue. 4psi- psi 2800 rpms - 3200rpm?

Post by dillonr92 »

So In my 92 turbo legacy. Since I put the td04 in I've had a bogging issue around 4 psi to 9psi. And around 2800 rpm to 3200rpm. After that range it hits 10+psi and little higher rpm then pulls great. I've checked to see if there is any leaks everything good there. it holds pressure and boosts no problem. But it Boggs hella in that rpm/psi range.. I'm stumped.

Can you tell us a little more about your setup and how long has this been happening.

When you swapped in the TD04, did you also install the TMIC? Do you have a 90 degree silicone or rubber adapter on the turbo inlet?
