I had my feul pressure set at 50 psi with 93 octane and it ran good but now since the weather has has gotten colder Its running realy lean. My air feul ratio drops after vtec and the car stops pulling (I only did this once) I am thinking about installing an external feul pump to try to boost the feul a little but I know the injectors will only flow so much. I was also thinking of running h22 injectors. Let me know what you guys think about this.
