Use the fuel calc located in MT. IT works fine. I have been retuning mine and it is working out fine. I also updated code so i cant be sure but i get a much better idle as well. I can idle smoothly at 15.5 AFR.
Start over. Any info you are following from Slick was not 100% accurate.
you numbers are wrong i can tell you that! my 550's are 6.4 and 450's should be 7.4
