Update The new FAST wideband is working fine and I was able to take a test drive with the 62 primary jets (versus 64's) and the 8.5 "standard" pv (versus 9.5 High Flow).
The 64 to 62 primary jet swap brought the A/F range up into the low 14's above 3500rpms. I think that I will leave it alone for now. I keep changing the range that I would like to be driving in but for right now, I like the 14.0 - 15.6 cruising A/F range.
The 9.5 HF PV (high flow per Quick Fuel) swap to the Standard 8.5 power valve did not help my 50/55mph to WOT rich spike like I was hoping. The rich spike stayed in the 11.8 to 12.2 A/F range. The 62 jets did not hurt my WOT A/F number, it was still at 13.0 at my shift point. It also took away from my low end power at WOT. I am going to swap back in the 9.5 HF unit and then swap my secondary squirter from the current .031" all the way down to a .018" and see how the rich spike acts. The above was done in 80 degree temps with very high humidity. We are supposed to get into the mid 90's with high humidity, so I am done for the day.
