I just added the MHD BEF w/ JB4. I like the combination. Car ran great before the plug change yesterday. My previous plugs were the same NGK's. These are 1 step colder.

That would mess with the HPFP? I could check the coils again. Only thing I can see in the logs is the HPFP diving as the RPM's go higher. Also IGN6 is lagging, that's probably the coil.
