Another thing I noticed from your meth-off datalog is the Short term fuel trims seem to be maxing out at higher rpms.

Isn't 34 the upper limit on these?

And that's at less than 10psi at that point?

There is also a differential between the trims on bank 1 and bank 2, but that happens on the procede too.

Not sure if you read the stage 2 thread at all, but boost <5000 RPM is inaccurate. We need to start logging "requested boost" to show you guys what the proper curve is. It's 18 psi down low/midrange tapering to about 13-14 psi at redline.

Yea curious. What's weirder is the fact AFRs were in the 12.0 - 12.2 range when I first installed the tune last month but now it's in the 11's. Funny, I romped the hell out of it after the tune reinstall/install and the AFRs have settled back in the 11.3 - 11.6 range.

I disabled the external downpipe fix and I doubt I have a boost leak since WGDC is within spec. The last thing to do is replace the DCI cones (on order) as they are all beat up and filthy, but there's nothing really different from a one month span. No codes thrown, no other issues to note. Just a richer AFR than target.
