WW2 learning curve on stock turbo?

ok I had a friend that installed a WW2 on a stock 05-07 turbo. After that he had max boost issue being that they where low. No leaks on the exhaust side on intake side. But after a period of time his boost came back. Now fast forward. I rebuild my stock turbo and installed a WW2 in it. Since it got into the 30s today I went out and swapped the powermax out for the stocker WW2 combo. I see the same thing on my 04 turbo as his 05-07. It's not a exhaust leak, and I know it's not a intake side leak either. Boost vs MAF look about right and bottom end and crusing is good. I even swapped out the VGT solenoids and same thing. I see about 22-23 until it the converter locks then I see 25-26 for a second or two. If I went back to the Powermax or the stock compressor wheel I would be fine again. Since this is the second turbo that has done this I'm pretty sure it has to do with the wheel. I just wanted to throw some feelers out there for those that have used these before because it's about to become a desk paper weight.

When I had my WW2 on my 05 I saw lower boost pressure my it had a bit more power. Got a little better mpg's spooled a little quicker seemed more efficient I guess. I think about 26 or so was about the most boost I saw with stock gage

That's about what I'm seeing with the same turbo Erick had on his truck. About 25-26 max.

Yeah, I'm seeing the same numbers.

I'm not sure the WW2 is supposed to increase boost psi, but rather increase the density of the air and do it in a quicker way, decreasing spool-up time...

Ok, so I'm not the only one. Well I need to run some more test and maybe even go back to the cast wheel or a KTS wheel. I'm not concerned about boost because so many things affect it and a crappy running truck can have high boost. What I am concerned about is MAF numbers. on a side note a stock turbo with a WW2 so far is flowing around 400-420 g/s MAF and the powermax with SP billet flowed 460 g/s + MAF. Also I'm not sure spool up is much quicker than the powermax billet combo. Anyways off for more testing.

I rolled back to stock tonight and my emissions still function. I'll be getting some MAF readings to check again cast wheel MAF readings.

Ever wonder what the PCM does?? Using all the sensors it makes adjustments. Watch VGT% and note the differences.

I'm not sure how to take this.

Just another suggestion for answering your question. Everyone forgets these trucks are controlled by a computer. Consider the changes you made. Why is it you only look at boost PSI?? There are several sensors the PCM uses and will makes changes. Just cause truck X made 30 PSI boost, doesn't mean truck Y will do the exact same thing.

Wow talk about arrogance. Well considering I've used all the strategy's cyh0-7 on my truck, I've used three difference wheels in the powermax, and now two in the stocker. I've data logged difference in air intakes, intercoolers and other part changes I'm pretty sure I know how and what the ECM does or doesn't do. I'm also versed depending on which strategy I run how long the learning curve is on the ECM or TCM. I also know boost is a piss poor measure of air flow given everything that affects boost. heck I've even programmed the Accell DFI system on my old Vortech XX mondo supercharged 93 mustang back in the day. This thread was basically a feeler to see if others where seeing the same thing that's it nothing more. But hey thanks for the input.
