Problems while in REGEN

[ST310]

Has anyone experienced this problem while in REGEN?

boost pressure wont hold steady and it just keeps dropping and coming back up while holding steady throttle on even grade. While this is happening, ther is also a load noise that sounds like an air leak coming from the passanger side of the cab (radio antenna area). Everything goes back to normal after REGEN has finished.

I get the same thing during regen. I believe it is the VGT turbo actuator allowing the Temps to get hot enough for the regen. I see the EGT temps go all over the place when in regen. As for the air sound. I get it too but am unsure where it is coming from. After regen completes it goes back to normal. I will be getting my Turbo back exhaust next paycheck so good bye regen.

Nothing good occurs while in regen period!!! Do a DPF delete and save your engine and the environment!!
