you need to be running "super" regardless..........

most JDM tuning companies were renowned for very aggressive ignition maps, etc and so in general its not really a good idea so simply fit and hope....... it will need AFR's, etc checked as a minimum to guarantee its "safe"

the 'chips' were burnt on the bench and are basically a one use / throw away item - if you needed to change something then you burnt the next chip
