Help with boost/compressor surge

Hey everyone... I have a 02 7.3 with stock turbo and injectors. Truck has 182,000 miles with the 6637 intake mod, CCV mod, Foil delete mod, 3.5 pipes turbo down straight pipe, Dp tuner and boost, pyro, tranny, volt Gage's. running a 4 inch lift and 35 inch muds.

While pulling big hills at about 14 to 16 pounds boost I'm getting a flutter noise and cut out of boost and boost drops to 12 or so... Goes away once I shut off over drive and jump down a gear... This happens more often if I'm running 60 hp or 80hp then stock mode on my chip...

What can I do to fix this?

Get a WW or WW2
WW2 is sold by diesel site and will fix your problem while adding performance.

Do it asap because surge will KILL your turbo

WW2 is the way to go. WW is simply a pre-99.5 wheel. It will fix the surge at the cost of a couple pounds of boost. WW2 will fix the surge and provide better boost. WW2 is what I'm looking at as a replacement.

From my understanding, it's the next best thing to a 38r. Basically the WW2 maximizes what our stock housing is able to produce, within acceptable RPM limits. They are making the WW2 for the 38r housing as well, for what it's worth.

As someone not in the know, it looks like a 1st gen wheel that's been polished like a mofo with the addition of nice little air grabbers in the null areas. Polished is good, more air grabbers is better.

For sure it looks like the wwl is rough surface with more vains then my stock wheel and the ww2 has even more vains like you said and is polished... Pricey but hey if that's what I need then that's what I need!

Pricey is relative, but like I said, it's on my list. It's cheaper than a 38r, and my plan is only for Stage 1. If I were planning larger than Stage 1 injectors, 38r would be on my list.

As a reminder, nothing is cheap on these. The WW2 is almost the cheapest mod you can go. Top 5 for sure.

Yea I hear ya... I'd love a bigger better turbo maybe someday but for now I think the ww2 will solve my problem and help out a bit. Are stage 1 injectors like the next step up from stock ones?

Stage 1 is the next step up. WW2 should supply them with the air needed, with associated tunes.
