I'm finally putting my boat in the water this weekend. Unfortunitley  I lost the tune from the dyno so I'm going to have to tune it on the water by data logging it. It is very rich and ill slowly be taking fuel out of the map until the air fuel ratio is dead on. I plan on fouling at least on set of plugs before I get it close. I'm going to run hot plugs till I'm close on the tune then switch to cold. It is a bbc alum heads with a fast efi. very well built motor. very large roller cam. 300 shot no2 but not hitting it till I have a good tune.


What pugs do you guys recommend using. Brand, style heat range ext.
  Thanks Jimmy.
