I have an Apexi AVCR in my car. I can do a pull and and then go back and read my last highest recorded settings (boost, injector duty, and throttle position). Id say 20% of the time the the injector duty jumps to 100%....I have the injector duty set at around 51% to reach my 17-18psi mark. So my question is, why does the injector duty spike sometimes???
