I got my chip on and I been messing with it figuring out how the truck reacts to certain tunes.

I noticed on the higher HP tunes, when I let off the gas the turbo surges.

Is this a bad thing?

Will it tear anything up?

And how can I fix the issue?

If its barking when you let off the throttle just ease out of it. All that boosted air has to go somewhere if you go from 3000RPM to 800 rpm in .5 seconds.
