Well, after playing with my A413 governor, here is some shift info. First time, used the TBI weights-both solid, and the blue spring with 7 turns of line pressure. Also using the Sonnax governor kit with the turbo heavier spring. It would upshift at 6200 rpm or not at all unless I floated the gas. 2-3 upshift was nice, not too early, sorry, can't remember MPH. So last night, changed the setup, I used the TBI small weight-solid, turbo large weight-hollow, orange turbo spring and the Sonnax turbo spring. Now it shifts at 5000 rpm and the 2-3 upshift is low. If I get motivation, will take it out again tonight and change some stuff, I want it to shift around 5800 rpm! Wish they were easier to remove!
Heres what I did and now shifts at 5800 rpm, woo frickin hoo. Went back in and changed the orange spring to the blue one. Changed the Sonnax spring with the lighter 4 cyl one. Now shifts at 5800 rpm at full throttle. Line pressure still at 7 turns. 2-3 is great. I made the tv cable one click higher as light throttle shifts were ugg. Now great. Hope this helps everyone and doesn't have to go what I went through.

Here is some info. so you don't wast any time on the things I have. The little valve (primary) controls the shift points, so the heavier the valve the lower the speed the shift points will happen, across the board. The big valve (secondary) controls the higher (road speed) shift points. It does this by feeding some fluid pressure to the back side of the little valve at higher road speeds that counter act the centrifugal force (hold back) on the little valve. So making the big valve lighter or the spring for it heavier, will lower the WOT shift points.
Get the shift points down, then raise the line pressure to get your shift points where you want them. Drill a hole in the case inline with the line pressure screw and tap the hole for a small pipe plug. You now can adjust the shift points from outside of the trans with the line pressure.
