that is just a suggestion by innovate. I understand that every program or combo is different. their suggestion worked for me. I could of set mine at 12.5-15:1 as it idle the same, but I ended up with 13.5-14 which is right in the middle of their suggested target.
you mentioned getting it dyno tuned awhile back. well what do you think they use to tune your carb with for best a/f setting? an a/f meter. theres reads out on a pc screen, mine reads out on an in car gage. same tool
