The small one that is connected to the exhaust manifold so it doesnt overspin and possibly blow up. Visit some of the diesel forums to learn how it is done.

The engine computer (ECM) ( on the driver side of the block ) and the powertrain computer (PCM) ( on the passenger side of the firewall ) are the companion modules.
No, not from the factory.
The normal direction of airflow is air filter to turbo, to intercooler, to engine.The normal direction of airflow is air filter to turbo, to intercooler, to engine.
This is a staionary part of the turbo and converts the presure of the exhaust gases to kinetic energy, i.e. speed, and direct it to the blades which is the moving part of the turbocharger. Consequently, on the other end of the shaft there is the compressor which draws air and sends it with high pressure into the engine combustion chamber.
Boost level is controlled by the wastegate on the turbo. The wastegate should start to open at 15 psi and fully open at 20 psi. This is to keep from over boost that was set by the factory.
It screws into the turbocharger. Look for wires running to the turbo.
Integral part of turbo.
Check your exhaust manifold. Cummins uses one that shrinks and then cracks. If exhaust is getting out before it reaches the turbocharger, you'll get low boost.
The resonator is a "muffler" used in the turbocharger plumbing to quiet the turbo noise.The resonator is a "muffler" used in the turbocharger plumbing to quiet the turbo noise.

Hitachi built HT-18 Twin Scroll turbocharger capable of operating at 12-14psi max. limited to about 6psi by the stock wastegate.

Code p0234 means turbo overboost, my truck just started doing this tonight and I'm doing research to try and figure it out. I found already that p0234 has to do with the wastegate. I found mechanical wastegate failure. I'm not sure what that means but I'm doing more research, ill post again when i find out more
if the turbo is the factory equipped turbo and not an aftermarket/performance turbo, your wastegate solenoid may be malfunctioning or you may have a vacuum leak somewhere. Your turbo's wastegate actuator is run off vacuum, and it controls boost. If the actuator never actuates, the turbo will make way too much boost.If it is a performance/upgrade turbo, surge is caused by poor turbocharger design. You have to send the turbo to a turbo shop to fix the surge issuehelp@coloradoturbo.com
