EDIT: Pretty much ignore this post as i cant delete it. My $400 scan tool cant access IAT2 or pressure sensors so this whole idea was a bust.

Haven't posted here in awhile, after sitting on my 06 GMS2 LSJ for a couple months i decided to start going at this "low boost" BS again. Ive been more active in the "Cobalt SS gang Ohio" and "ZZP Fanpage" facebook groups and ive had alot of things suggested to me.
Ive replaced the bypass valve and messed with it half a dozen times and got it to read as high as i could, Ive installed a new ZZP Stg2 belt with no change. Someone asked if my OEM gauge was working as his failed and wouldn't read past 10-11. Which just so happens to be where mine stops reading.
So i went got got a code scanner with Realtime readouts and spent the night romping the absolute **** out of this thing. Here's what i found.
Under a 2-3 WOT pull, MAP reads about 51inHg which i have no idea if is anywhere near correct. cruising highway speeds its down in the single digits. IAT no matter how hard i romped it NEVER got higher than 71. Which i also dont believe as it was 60 outside this night. spark adv under WOT bounces between 21.5 and 23. When just cruising highway speed spark adv floats between 30ish and as high as 40-41.
Im not too sure what these values mean but im sure SOMEONE here does. I dont know what else to do. I Can go out again and look for more readings if needed.
EDIT: Im not sure is the MAP readings i got is from the inlet side of the blower or the one on the edge of the intake manifold.
