Some more experience with the PP6 and NA tuning......
My 1990 Legacy has been getting CRAPPY milage, like 16mph . And over 4000 rpm just runs out of poop REAL bad. The motor is "fresh" and shouldnt be doing this bad. The plugs and air filter are new, oil is new, and no CELs... I considered changing out the O2 sensor, but since there are no CELs, and the O2 sensor is out of the loop at WOT, I skipped replacing it for now.
Anyway.... I have an extra PP6 thats been waiting to go in another sedan I am going to boost soon and I just snagged it and installed it into the DD wagon.
Presto (ok, a bit of driving) and I have been able to pull out a fair bit of MAF signal at idle and cruise to lean out the mixture some. And power wise, I was able to figure out I was running lean at WOT over 4000 rpm. I added just a tad of fuel (+3) in the cells and it smoothed out considerably and the misses/flat spots are gone. I still have some/ALOT of messing around to do, but I am super happy at the quickness of getting rid of the issues I had.
And the nice thing about it being NA is that there is about ZERO chance of blowing a piston if I screw up!

Cool. Any ideas as to why it was running that way before the install/tuning?
