Is a stock 6.0 suppose to have compressor surge?

As it says above, I had some compressor surge. I've heard it called ten different things, but it's that cha cha cha sound after you release the load on the motor. I was pulling a stump out and was under maybe 8-10psi of load and got out of it real quick, honestly it spooked me alittle, never heard my truck do it before. I searched around on the ORG and google, couldn't really find an answer, so will a stock 6.0 surge? Is something going bad? Thanks guys.

on a stock truck you should not have any turbo farts what so ever. You may need to clean it.

How many miles? is it the original turbo?

150xxx, yes it's the stock turbo, I've only had the truck since June and I've put 8k miles on her. I need to clean it probably. I rolled my strat back to an earlier one, so the VGT doesn't cycle at idle, think it might have made it dirty?

Ford has a flash that will move the vgt vains to keep them from getting stuck. You may not have the flash. It is not a big deal to get it just for that.

A stock truck will have the turbo fart.

Well I just got PHP to roll me back so I could get away from that flash. It's back to the ECM strategy that it had when it rolled off the factory line, trying to gain some MPGs. I'll just clean it and see what happens after that.

If that is the only time you have noticed it, then you are fine. You should be able to duplicate that noise any time you want. It has nothing to do with the fact that the turbo needs cleaned. It does it because there is no waste gate and the pressure back feeds through the intake when the vanes close quickly, like when being under a load and being completely released. Just the nature of a 6.0. Unless you are having an actual problem, I wouldn't waste my time pulling the turbo.
