I cleaned the EBP tube and cleaned the EBP sensor.
what else can i check to see why my truck does not make that wonderful jet engine afterburner sound.
I don't really want to buy a new sensor without making absolutly sure my sensor is bad and it not somthing else.
what is the neccessity for starting your truck in stock mode
Lower ICP or something I am not sure about. Just know that Jody said in the winter that it is best to run the truck in the stock setting until the engine is warm. Good enough for me. I am pretty sure that is where this comes from.
Are you having issues just while idling or while driving?
I noticed mine started to take a little more pedal while driving to open the valve up as my turbo up pipe leaks got worse. If you don't have any up pipe leak ( I would be shocked ) then there are tests to pinpoint the cause. There are a host of components interacting for the EBPV to open and close.
You could disconnect the solenoid on the EBPV at the turbo pedestal and see if it instantly opens up. If it doesn't, it is stickng or binding. And I would focus my troubleshooting starting there. If it opens up when pulling the electrical connector there, it doesn't rule out that part, but then all the tests will need to be performed on that system.
