Thread: PE nuts

you should never ever max your injectors with your amount of mods. is it possible that one of your injectors is fubar'd or your fuel rail/line is kinked in any way?

i didnt really look, but how does your timing look? are you commanding something like 30* WOT?

I don't believe I have a fueling issue. I have no misfires recorded, and as the PCM commands a particular AFR the O2 sensor is showing its achieving that AFR. I'm just wondering why I need such high O2s to not knock.

I'm going to do some maintenance at home. I'm about to order PRJ wires, AL605 plugs, and a new O2 sensor. If that doesn't fix it, I'll do a fuel pressure test. Depending on the results from that, it might be time for new injectors (since I was planning on swapping to 04-05 L67 or maybe L32 injectors anyway before I start moving towards more mods so I always have the headroom).
