I've been reading this since I'm also running a P-S 1000HP on my 414 that was originally on my 517B. Mine isa 3 circuit primary plate and the small block needed just a slight amount of tuning to idle. It's a "typical cold natured Chrysler Product" as one of my old mentors used to always say, once it warms up it seems fine. I think I'm at 88/6.5 and 94/plugged F/R, I've wondered would there be any major benefit to plugging the primary and square jetting (since I'm Foot-braking at 3000 off the 2-step so I'm really just launching off the Back shooters anyway). I'm thinking since the PV is vacuum/load sensitive just square jetting it might be more consistent and may actually make a little more torque. Thoughts?

BTW... I have nothing but High praise for Patrick, I gave him my BB 517 to SB 414 parameter changes and he told me where to jet.
