alright my truck started this whistling sound,and power loss, it start's at about 2000 rpm when driving but when the truck is still and you rev it up it don't do it.i'v check'd all the clamp on the intercooler tube's 3 or 4 times, could this be the wastegate since it don't do it except when driving??

 

What Are We Looking At For A Truck Here??????????

 

2000 3500 ram

 

This came up not long ago, you might check the bolts on the intake plate top.

 

i'v check'd that it's ok so........??

 

Is there any codes? Normally if the wastegate is messed up you will have overboost codes which it may be. If the truck is stock with no boost fooler and the ecm sees to much boost pressure it will defuel there that would explain your loss of power. how loud is the whistling noise?

 

no codes ,the whistling is no problem to here over the motor, and it's got straight pipes

 

and it's stock no mod's

 

you could try pressurizing your intercooler and plumbing with regulated air pressure then use soapy water to check all the connections if it is a boost leak and you pressurize the system with the engine off you should be able to hear the leak. hopefully your intercooler isn't cracked. another thing you could do would be to hook up a boost guage and see what your boost is at.

 

thanks man ill try that tomorow

 

You might also check the plumbing going to your wastegate diaphram...loose elbow/cracked line.

 

discoved that the intake gasget had a tear going to fix that in the morning that should fix it, thanks for the help guy's!!

 

did the gasket fix the problem?

 

Wastegate may be stuck open.

 

nope the gasket did not fix it, so???? any ideas
