Yes, it does. Previous had a standard T3 with -34 actuator (act almost brandnew) and was peaking at 26 psi and holding 18psi.

Now bought a brandnew T34.55 turbo which peaks at 32psi but only helds 18 psi at 6000rpm in fourth.

Thinking maybe through the bigger exhaust housing it should need a bit more preload because off the extra build-up from exhaust gas pressure at high rpm but dont know for sure..
