Best source for wastegate actuator
Today is the first day I hammered down on the truck since I installed my boost/egt gauge. Egt's got to 900 but boost went to almost 30. Obviously my wastegate isn't working. I didn't think a stocker would pump enough fuel to reach that figure. I haven't had to time to diagnose the wastegate problem but more than likely it is the actuator don't ya think? It wasn't stuck when I installed the engine back in November.
If it turns out to be a bad actuator is there one available from the aftermarket that's better and/or cheaper than the stocker? If not, do I order one from Cummins, Dodge, or HTT? I assume there is a difference in the actuators because the autos develop around 18psi and the sticks push 23 or so. Should I ask for one for 215 engine?
Also, if the actuator is bad can it be leaking boost? I assume they work kinda like a vacuum motor in reverse with a rubber diaphragm.
