If it's reversed, you have way too much fuel there. And it only slightly begins to tapper out when you open up the secondaries. In either case it doesn't sound like you have a way to control the fuel for the upgraded injectors.

yes i dont believe there is anything to control the fuel for the upgraded injectors. it only runs bad at low rpm once it hit high rpms it seems to be just fine. i'm not really sure what to do so if theres any advice and pointers on how to do something to fix the problem that would be great.
