Don't ever pull out the precat O2 without setting it up in the tune to not use the O2's and be in open loop
Hopefully yours is old enough that it won't go apeshit bonkers. Put the precat back and reactivate along with the rear O2's still being installed. It'll need them to verify the front O2's operations and to know it can rely on them. Drive it a little like that at a highway speed for 20 or so mins. Should be enough for it to run it's "self verification" test. After that, pull the rear O2 or install a precat O2 bung and put the wideband in there. These things - depending on year and OS - will divert to using post cat O2's for fuel control if it sees a complete failure or loss of the precat O2's. Been there, done that myself even though I didn't know that was a thing until that point.
To shape the torque model - install the stock model. Take 30% out of the furthest left, then 27ish percent, then 20 then 12 in the map and airmass models. Make sure to do both. Smooth 2 times from 1600 to the left. That should get you in the same-ish part of the state.... Make sure for the negative numbers your multiplying by 1.3, 1.27, 1.2 and 1.12 to make them more negative and then the positive numbers by the .7 to make them more negative.
Myself and others offer remote tuning too, if you decide you want to go that route.
