" What I find with too low of a power valve in most cases is tip in stumble because the PV circuit is delayed too much, and no amount of squirter tuning will get rid of it. You might be able to bandaid it and cover most of it up, but the PV is the real cure and will also help mid range throttle transitions. My engine still likes 6.5 PV's in it front and rear. Even trying 4.5's creates an off idle stumble."
I've had this issue which was caused as you state by too low # power valve. I chased this issue for months, years ago. Very informative post... Thanks Larry!
