turbo "huffing" sound after i throttle hard then let off????

[HICKatvRACER17]

So it would only do it when the truck was cold, now it always dies it. If I slam on the throttle then let off all the way it will make a huff huff huff sound. What is this from, just put in livewire w mpt tunes, but I think i noticed it once after my fender bender before I put in the livewire. Egr delete isn't in yet, gotta find time to do it.


Also, i know theres a lot if talk, but who should I talk to about diff tunes? I want the best race one, best economy one, and a good tow one. Not sure if I like the mpt ones.

Thanx

The huff huff huff sound is normal. There is no wastegate so it has to dump the boost somewhere, That somewhere is back through the CAC tubes. The noise becomes more noticeable when boost numbers are higher like when running a tuner. I know mine becomes more noticeable when my in-line module is in as opposed to when I'm just running stock.

who is MPT? try some innovative or gear head tunes can't go wrong with either of them

I know that my '04 would do that constantly after I had some work done. Took a look in the engine and noticed the EBP Sensor did not get plugged back in. Took care of that and problem solved. Might check the sensor...

Has nothing to do with any sensors, it's the un-used boost being let loose back through the intake tubes.... It's perfectly normal... Ricers have blow of valves... Diesels have turbo farts :p

A bad EBP Sensor can cause this when generating low boost numbers.

I'm curious as to how you thought this thread was a good place to post up your question?? When it has nothing to do with belts at all....

Start up a thread of your own about your question...
