Turbo Bark

[NMDuramax]

Is there any way to tune out the "turbo bark" that is associated with letting off the pedal? I am running a mild 50hp tune that gets good fuel milage and doesn't over load the tranny, and provides me a nice powerband but the turbo bark is driving me nuts and I know that its not healthy for the turbo. I am not new to EFI Live but I am new being on the tuning modifications aspect of the table. Any help would be great!! Thx!!

If you're willing to post the tune, there are quite a few of us here that will take a look to see if anything looks out of place...

Give this a try...Open the tune and click on "History" to see what tables were changed...More adjustments can be made...

Do you still have the turbo bark?

[NMDuramax]

No I took the tune that you sent me and tweaked it some more and the truck runs great now!! Thanks again!!

Do you know what specifically was causing the bark, or what changes you made specifically that stopped it? Thanks!

I'm guessing A0101...

Yes, it was the desired boost and the target vane position tables that I messed with. I had to smooth out the vane position table cause it was too aggressive!!
