Default LS1 Edit + shift points

Can anyone help me understand why i was able to set my shift points exactly where i wanted them with the stock rear end, and now that i switched to 3.73's my 1-2 shifts prematurely and 2-3 blows past my MPH to my rev limit??? I have a 2000 SS w/ Aubern diff, had 3.23's now Motive 3.73's.

I sure did. I just can't figure it out. Esp. since it worked just fine with the 3.23's and now is screwy with the 3.73's

By part throttle, what are you meaning. I did adjust most if not all the shift point across the whole throttle range on the chart and I matched the Performance, Hot and cruise to the normal chart. Is there something else?

what i did was only move your MPH
dont touch the rpm, leave it at 6000.

if your hitting the limiter, lower your mph until it shifts where you want it.
i have mine right now at
1-2 35 - 6000
2-3 65 - 6000
