Another thing HKS said was to be sure to set partial throttle boost parameters to prevent CELs from coming on. This is what they recommended:
30% throttle, no more than 90kPa
40% throttle, no more than 110kPa
50% throttle, no more than 120kPa
60% throttle, no more than 130kPa
75% throttle and above, no need to limit
