well i wont know for sure until i get home and look at it for myself. but thanks for all the help and the calculation. ill bring the post back up after the new year when i get to look at my dyno sheet myself. ill also post the dyno sheet..... as for my air fuel i had steady high 10s and once it hit 6k i had low 10s, high 9s so it was rich. i am going to put my downpipe and adjust it better and dyno again. hoping for the 320rwhp range. if i dont make it, greddy fmic next with alum rad.
