Its not the timing. Its the fuel, actually the wideband is fubarred I think.
I've only had the blower a couple days and I've only had 10 hours off between trips and been on the road 2-3 days at a time. I'll have most of this week off and will get it tuned correctly hopefully in time for opening day at the track on Saturday. We'll see.

Engine is exhibiting lean symptoms.
Wideband is showing rich conditions, however as engine speed increases and the wideband shows an increasingly richer burn, the factory narrowband is slightly dropping in voltage.
I'll be off work soon and should have time to play with it for a while tonight.

can you swap out your factory 02 sensor at all?
i got frickin box of them, but i bet you dont have any....
when the WB dies, it wont read rich, thats just not how they die....this is strange.
can you send me your logs, I'll stare them over.
you should have me e-mail from the fuel e-mail i send you.

well just as back up, i always believe the narrow band over the wideband....factory equipment is rarely ever wrong when showing just a general conditions.

I'll mess with it tonight and give you a better idea.
damn no vids... I spend all day working on fueling my car, and still no vids lol...
but anyway, that damn walbro pump actually fits quite perfectly... just need to cut back the feed line (grey plastic part) about 1/4 inch and mill down a plastic tab on the inside of the top of the canister and wala... even the harness is the same... so far at 18psi... 11.4:1 across the board, and my fuel pressure is back to 58 psi.. woot
