I've seen alot of recent threads where people are just jumping into BM3 and are saying that they should swap plugs to one range cooler for the OTS tunes on stock turbos. Why is this recommended? I've always understood that unless you are running some retardedly high boost or big turbos i.e. 500hp+ builds, factory plugs are sufficient.
currently running FBO, catless, bm3 stg2 93 for 7k miles and have seen no issues in logs or timing that are not related to fuel quality.
