Just called dynojet and they told me to use the Two Bro's slip on map map with the akrapovic slip on pipe. Just take the 0% column and highlight it from 2000 down to redline and change it from 0 to 40. They said that this should remedy the blue flame pop on deceleration. I have an appointment scheduled with dynojet to have them make a custom map for my bike. I will post the map when I get it. I am really happy with the performance that the slip on akra and K&N brings. I am smokin 750 gsxr's drag racing!!!!
