Choosing a stall will be dependant on your needs from the truck. Do you tow? Want to cut a killer 60' time? Etc

Aftermarket stalls lock up quite a bit firmer than stock. Remember these vehicles are built for people of all shades of life... a soccer mom probably won't want a stout TCC lock up...

If you change the lock up valve in the VB to an ON/OFF only (eliminate that PWM shit), it will shift quite a bit firmer and with more authority.

Don't have the line pressure toned down for street, keep it the same for all. Should be quick and tight at all levels but not harsh. The big trick to keeping the 1-2 down is the Sonnax accumulator valve train part (with the softest spring) so you can use a larger apply servo to prevent band slippage. The rest of the shifts are easy to setup. 3-4 needs to be fairly large, .110-.125, it's a weak shift anyway. 2-3 .110 seems to work well for the street, .125 may be okay too. 1-2 don't drill the feed hole at all.

Mind you these are on stock clutches/stock band.
