I just went through getting turbo surge with a 6637 air filter/4" exhaust/PHP Hydra tunes. I cured it completely with the Full Force Diesel billet wheel thanks to recommendations from this forum. I don't know if this particular wheel fits the van turbo.
I wasn't able to hear what your turbo was doing. Here is a great example of turbo surge I found from youtube. Mine sounded just like this.

It would still bark during a gear change if you had a bunch of boost built up.

So listening to my videos now today I can tell my video didn’t really show it very well. It’s very noticeable in the cab but hard to get on camera. It’s almost like a surge but only happens under a load in 4th gear. Tried to get it to do it in other gears but it refused. About 11psi it will almost start like a buffering sound and will start slow and get worse as more throttle as applied and the boost goes up some more to about 15psi. Then it really buffers but still fairly quiet compared to other surge videos. Doing reasearch on this forum it looks like someone tested ww vs stock and ats housing vs stock. Turns out the ats and stock wheel turned out with better spoiling and more boost and no surge. I’ll wait to see what my new tuning does but sounds like a ats housing might be the best to solve it.

Yeah the compressor wheel is much cheaper. I’ve read the billet wheel is a lot louder though. Mines pretty loud already can’t imagine it getting much louder though.....I have a Donaldson 6637

The ATS housing adds more noise than a billet compressor wheel will. If you want a quiet wheel look into a billet 9+0 or 11+0 blade design. The stock wheel with an ATS housing is much louder than stock. It sounds good though. I run an ATS housing and a 9+0 billet wheel with a 6637 filter with no noise complaints.

During my build process I noticed pronounced surge while towing (22,500 GCW) in 6th. At the time I had the Hydra/6637/4" exhaust. I could put the Hydra on the stock tune and 80% of the surge went away.
The FFD billet wheel eliminated surge and now I can tow that same load with zero surge plus I can use any gear/throttle position. That lets me use the power above where surge was occurring. I do have to watch the boost gauge a little, I don't want to tow and boost over 30psi. I have to really push the rpms and load to worry about it. EGT's are just over 1100 pushing it on the Hydra 65 hp tow tune.
Once you get everything sorted you are going to like the power!

My turbo is loud now but it’s not terrible. I just would prefer it not get any louder. If anything if I could get the engine drone down a lot quieter then that would make a huge difference. Sounds like the wheel is the best way to go. I was wondering if the hydra would make it worse sense it’s better tuning. I realize that the tuning can cause it but also not really their fault since our trucks were made to run on 235hp not whatever we are running now. Is it ok if it surges some while driving? It’s hard to have a part shipped for me when we are on the road a lot and trying to login up the next place.
