Hi guys i own a 92 Rx7 JDM (Fd) and I checked on my ECM and there's a Nerve Essential Sticker on it... so it's chipped i Checked on the Web and found a Webpage of that Compagnie but found nothing about that Chip

so i'm wondering if one of you knows something about that chip... to know what it's does . I know that it's modified the Mapping.... but i'm wondering if I can turn the Boost up a little bit.. if it's safe... because i know with a Stock Ecu i can't boost over 12 Psi

thanks for your help!
