I'm running around 5.5 LSN and 3.5 HSN consistently with P3 plug temping around 185 - 190 good smoke excellent power; engine runs great. Sorry my numbers were way off for ya.

Check this out before you start running your LSN too lean. Also, it's always a good thing to use the search feature of this forum you will typically find answers to your questions before you have to ask them...
