Do you have 4 1200 injectors. Your tuning would have to be pretty lean in order to get into the 11's withonly 2 1200 injectors. I tried with 1300's, tuned for afr of 11.0 at 15lbs of boost and couldn't do it. My injector duty cycle was peaking above 95. I have since gone to 1600's and at 12 psi I am getting back into the 90 on my injector duty cycle. I will soon be shifting my primaries to 850's to pull those duties back down.

If you are indeed pulling those numbers and speeds make sure your duty cycles and afr's are inline.
