Since an intake makes the evo run way richer as dynoed by AMS, who here with an intake and SAFC has tuned the airflow down for it? I just put an air filter on my car and after driving a while it seems to be down on power. Then I checked about this and found AMS lost 30WHP without tuning the fuel So I want to know how much % did you have to change the AFC and at what RPM points to tune for the increased air? Thanks
