Secondaries now work, downshift speeds?

[AirSpeed]

I finally got my secondaries working, I thought they were working before but I was VERY wrong, my truck now hauls ass! I do question the speed at which it will downshift, if I am going 50mph or slower it will downshift instantly, above 50 it won't downshift at all. Should it downshift above 50?
After flooring the accelerator below 50 it will downshift and stay in 2nd until I hit 60 then it shifts into 3rd. Does this sound right? If not, what speeds should I experience an upshift and downshift?

I have had this truck since November and until today I thought the secondaries were working, slightly, I didn't have a lot of power at high RPMs but thought I had some other issues going on, after cleaning and adjusing all linkages involved in the automatic choke, once I got it all cleaned up and lubesd, the secondaries work perfect! I was so excited I went out and floored it a few times to feel all that hidden power! It's awesome now!
