Sound after EGR Cooler Delete

[redfishpowerstroke]

While traveling on the Interstate my EGR Cooler went out and I had to locate a shop to put a delete kit on rather than taking it to a dealer who would replace it, I'm out of warranty.

At any case, truck is running fine but when I let off the pedal there is a gas discharge sound. Don't know if this is normal but I haven't read about this anywhere and I have read quite about the EGR cooler delete. They test drove it and said it all was good so??? Thanks for entertaining possibly a dim question

hmmm how to imitate sounds with words.


does it sound like a fart like fart fart fart then goes away? if so thats normal. but only happens when wot then let off. ?

[redfishpowerstroke]

Not WOT but under power...the more the power and the more the sudden let off then the more the Gas sound....maybe a fart sound, kind of like an air brake sound (or what I thought was an air brake sound) on a rig at a stop. gradual let off = no sound I noticed it the most when the cruise was on going up an incline then hitting the brake to take off the cruise. I very rarely am on it WOT...don't know when the last time I was there. going to drive it again and report back.

so far sounds like it is the normal turbo fart noise

[redfishpowerstroke]

ok. the sound is like if you were to say pshhh. longer if you are on it harder. definitely continuous.. doesn't do it in the driveway but then again..boost won't build in the driveway. Sound like the turbo fart?

[psd_va]

no that dose not sound like turbo fart. do you have a boost gauge? do have good boost? it may be normall still mine kinda dose something like that too.

[redfishpowerstroke]

don't have a good boost gauge yet.. but the numbers on the stock thing they call a boost gauge are the same as before.. going to an aftermarket shop today and have them give a listen

I bet it only does it when it's cold or has been shut down for a few hours than fired back up. That is what everyone is saying is a turbo fart but it actually is the computer compensating for the cold engine. Basically the same as a choke on a carberated engine. Maybe this is the first time you noticed it but I bet it use to happen before as well but you didn't notice it. I use to here it before, than I did the egr delete and it seemed like it was much more pronounced. Anyways just drive it and enjoy it, remember it still is a dirty diesel. These things would run till they cratered if they never had so much electronics hooked to them
