And yes I will grab another log this evening and post it.
Right now, your data backs up what I stated my experience has been, which was the turbo is too laggy for the power output.
You mean this?
One made 388whp on 26.1lbs, the other 430whp on 25.6lbs uncorrected in 41* weather. Like I said, the characteristics of this turbo seem to be among the same vein as the MHI 18K's. I'm perfectly happy to be where I am on power so far, considering this is my first WOT map on 17* of timing @ rev limiter.

Update, was out of town for about a week so we just now got around to WOT tuning the last couple days.
So far so good, very preliminary tuning on 25.8lbs. This is the 1st useable WOT map from Chet.
Hot and humid day here in IL, so I'm pleased thus far. Seeing full spool as early as 3800, I floored it late in this log as you can see. Seems comparable to many MHI 18k's so far. Still on 93 and slowly turning it up. We're going to run out of fuel though, already past 85% IDC at high rpm, so I'll need to order a fuel pump at the least before E85. Stay tuned.

The graph he posted from English looks to start at the normal 2500rpm (hard to see on my phone).
His graph shows his run starting at a much later RPM. It would surely spool faster had he started at 2500rpm instead of 3600.
If I punch it in 3rd at 2500 or 3500 I can guarantee I'll be hitting ~25psi at roughly the same spot.
That's what I'm saying. Even though one run started from MUCH earlier, they both hit boost in roughly the same spot. Granted there might be a SLIGHT difference, but it won't be enough to really matter.

Wow this sort of blew up. I took more logs late last night, I will post them up late tonight when I get home from work, car spools to 24psi by 3850rpm. There really seems like something is up with the fuel system on my car. We're hitting 92% IDC on pump gas, and it's not making much over 400hp. Chet asked me to order a Walbro 450, so that's on the way from maperformance. Really hoping we can get to 450whp on E85 if we overclock the injectors. Not sure why I'm see such high duty cycle on ID1000's and pump gas currently.
