turbo whistle oscillates at idle

I have a 05 f-350 with 72k that Iíve owned for about a year. I recently installed a 4 inch turbo back exhaust with cat/muffler delete. No other mods. The one thing Iíve noticed is the turbo whistle oscillates at idle. It sounds like the turbo is spooling up and then discharging about every 30-45 seconds. The truck runs great and I havenít noticed any other issues. Just trying to find out is something is wrong or if itís normal for the turbo to spool up at idle. Just to clarify its not spooling up like it would at 3000 RPMs and my factory boost gauge doesnít move at all.

Most likely its just the turbo exercising the unison ring to keep loose inside. Sometimes mine will do it at a stop light. If its doing it repeatedly in a 30-45 second cycle, there may be something awry but it sounds normal to me. You probably didn't notice it before with stock exhaust

That's normal. It does it to keep the turbo vanes clean, they implemented that in one of the strategy's, cant remember what one though.

Thank you. What is the unison ring? I would say my truck does it offten so what might be the issue?

Union ring is what actually moves the vanes in the exhaust side of the turbo. They will do that on their own and different strategies will act differently

Ok good deal. Is that strategy any good? Ive been eyeing a FICM tune from PHP and if need to get a new strategy thought it would be a good time for that too.

You do not need a new strategy in order to get php ficm tunes. I have vxbc9n8 which is a "bad strategy" but atlas 40 works fine with it. My suggestion is get atlas 40 and don't look back, if anything get a sct tuner unless you already have a custom tune. A tuner can write a custom tune to a different strategy. Try the atlas 40 you will not regret it.
