sort of averaging experience from online ...
factory is 12.5-14 depending on year. adding timing will move the power higher in the RPM range, it's also good for more MPG. it can however start to hurt spool-up, where depends on your setup.
basically no one recommends less that 16deg total for any application ever. 18 is like the bog-standard for anyone with gov springs and turning screws. reading about ppl running 22-24 and some love it while some have turned back a few deg. race trucks run upwards of 36.
this is still my tow rig and i do love quick spool, but i also drive at higher R's with the gov springs and the 6spd has less drop in R's per shift. i maybe kinda do like to play some stupid games now and then too. figured 18 min, but i couldn't convince myself to do over 20. i finally just decided "screw it, I'll do 19 if i can't decide" ... but then with 12.5 base i talked myself into a whole number of deg change and rounded up. so 19.5-12.5 = 7
