I'm fairly sure my fpr is shot... Actual fuel rail pressure is off from desired fuel rail pressure at idle, especially when the engine is cold.
Debating swapping to an LMM pump.
What is involved?
Is this a good/bad idea?
Is it worth it, for the increased rail pressure? or should i just stick with the LLY pump and replace the regulator?
I understand i would need to have the ECM re-tuned ("Idaho Rob" EFI tunes currently, would have him do the re-tune if i do this cp3 swap)
Did a search and found this thread, but not much info here...
