Re:t25 wastegate
I've used about 3 t-25 dsm turbos and everyone spooled to 8psi on the nose, so either you guys have your wastgates not straight, getting a weak signal to the actuator, or simply a bad wastegate all together. If you dont beleive me go take off the factory boost solenoid on a 2g dsm and hook it straight up, it will spool 8psi all day long.
As far as adjusting it to lower it, you can put some washers on the compressor housing to space the actuator out farther, this will increase the length of the arm and slightly crack open the wastegate, this increases lag but will lower the boost. If you really have your heart set on lowering the boost to 5-6psi, and have a decent spool your better off getting a different internal wastegate. Chrysler K cars with the 2.2l turbo engines have wastegates set at 5.5psi and work great for modding onto other turbo setups.

Re:t25 wastegate
I wish i could find one though, what is the name of the 2.2l turbo?
Most of the turbo's were garrett T-3's with a different bolt pattern on the turbo flange.
there was also a Mitsubishi Teo4h - most of the (gay
)Dodge turbo car guys swap this one out for a Garrett. The mitsubishi turbo was used specificaly for more low end torque on non intercooled cars. They spool fast too. 280whp seems to be the limit for the intercooled Garretts.
