05 STi stage 2 data log results

So I finally did some data logging and pulled it up on excel spreadsheet. Let me know if some of these numbers sound right to you guys.

Weather: 800ft above sea level, temp 15F.
Mods: HKS turboback exhaust(catless), K/N typoon SRI, Cobb Stage 2 tune(OTS).

Results: 3rd gear pull- 93% throttle pos, 5k rpm, 17.5PSI, AFR 11.04, intake temp 48F.

5th gear WOT pull- 99.9% throttle pos, 4.3k rpm, 18.56PSI, AFR 11.04, intake temp 28F.

I have all the other numbers, but these were the only ones I was really concerned with. I believe my AFR is in tolerance if I recall correctly. Although, I am a little concerned with my boost. I know cobb's site says 17.5 plus or minus .5. Don't know if it has to do with me having a catless turboback or the K&N SRi or both. The most I've ever seen was 19.0psi,:eek: but that was only once while I was monitering. Feel free to shed some light on any of this. Thanks.
