Turbo Bark
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...

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!!
