Burping noise
When my 04 SD is on the extream race tune, I am getting a burping noise coming from what appears to be the lower portion of the engine. It is not the air filter when lifting off the throttle, it is when the truck is under load (hard acceleration). I returned back to stock and hammered the truck. Could not recreate the noise. Any comments or similar experiences ?

Sounds like "turbo fart", which by all accounts is normal when lifting your foot off the accelerator after hard accel. I hate the sound, but Ford says its normal, my truck started doing it after my first flash at 15K miles.

I had the same problem especially under load and after a little figuring found out the fins on the exhaust side of the turbo had desinigrated. still had boost and everything. soon as I put a new turbo on it worked perfect!

Denman81, you sure sound calm about that. How do you disintigrate the exhaust fins? FOD would take out the intake side of the fins first. What leaves the intake side and takes out the exhaust side of the fan? rc

Yes it does blow a little black smoke when the burping occurs. It's pretty loud and sounds like it is coming from the turbo area.
Maybe turbo stick. But it does not seem to lose power. Again it only occurs when the truck is in extream race tune not on stock.

I was talking with ID and they said my turbo may need cleaning. I have 60K on the truck and it is showing signs of oil residue in the intake and turbo tube. I am planning on doing the CCV bypass anyway. Could the turbo be hanging up when the Race tune is asking it to spin at the rate needed for extra boost ? Is the turbo cleaning a major project ?
