Lippy,
Thanks for your comments. I am gonna try to take this one step at a time:
1. increase restrictors to 73/76 (in addition to the 02 sensors, the car feels better and is not fighting me to get 4k-5k rpm as much. It kind of max's out at 5-5.5k rpm anyway)
2. I think that I will be able to move back down to 86-90 from 94 secondary jets when I get the WOT dialed in better. My understanding is that the best way to adjust WOT is hsab and pvcrs; the secondary jets aren't that impactful on the WOT so the fact that they haven't.
3. I think the right PV is 6.5 based on my vacuum gauge readings. Gonna try the high flow PV if there is no noticeable change after I change the pvcrs. Trying to figure out if I change to the high flow pv before I change the pvcr.
I haven't thought of hacksawing the plugs; that may be a bit above my pay-grade...not sure I would know what I would be reading. I have more confidence in my ability to read the o2 sensor than the plugs
