Default dsm 450s in 98 sh

i just put dsm 450s in a prelude sh 1998 model. the air fuel on the dyno is good tell 6k then it goes wacko. it lean out and gets rich right at 6k. it does this very quickly. uo and down up and down. this does this no mater what fuel pressure its at or and what vafc tunning.

i installed a 96 resitor box and dsm injectors. before this it ran fine. made 160hp on my mustang dyno.

why the heck did you put in DSM 450s if you are only making 160?
