High stalls work nice when you whack them with alot of power though.....I have my combo back together and the wot stall is crazy. At 6300 rpms when it shifts 2-3, it only drops to about 5700 rpms. Sure keeps the boost up! I'm seeing 15 lbs of boost and with a big shot of 75% meth, 25% water. One run like that and it makes all the high rpms at part throttle worth it.

I'm telling you, Dan. When the trans is warm and I jump on it through the upper RPMs, it's like a beast.

That is good. You must be making good power.

Only bandaid I've found to help is that TCI constant pressure valvebody, so I can set the TV cable wherever I want to raise the part throttle rpm shifts. I too played alot with the governor weights and springs to no avail with any of the part throttle stuff.

I know of the TCI constant pressure body, but I've heard bad things about keeping constant pressure on the trans. Dana at Probuilt doesn't recommend it.
