I've had the CEL for low oil pressure, I have logs of what my oil pressure is at WOT. But it doesn't matter what I say, I'm just a ricer.
What I was say is that the HPOP in stock form does not support 90% of the mods people do. Even with the 150hp TW tune, without injector upgrades or HPOP upgrades it will only net you 70ish hp increase.
