I had a similar issue with jetting after my 4 mil and porting... Denny at flotek had me ball on the money with jetting, and if I remeber I went from 300 with stock pilots and Toomey needles, to 320 or 330 with stock pilots and stock needle set to the middle...
I recently went to 28pwks and I'm at 155 main and 45 pilot. I forget which needle but I'm middle clip... I think it's a Jjh needle
