my fault! fat thumbs- 2007 xl883l EFI first year for FI. the PC5 was junk-for 2 years I rode with all the generic maps and it was a pig-supports solution? DYNO IT for another 200$? and now they want you to go back to OEM parts cause their product has problems (after all these years) The plugs? has anyone had problems with a hotter plug. I know what I get with OEM plugs hence the question.

That makes more sense...EFI became standard on all Harley's in 2007.
Yes why are you converting everything back to stock? What modifications have been done to the bike?
Check out DK Customs or Fuel Moto for the PowerVision tuner with Auto Tune. Many on the forum use them for a reason...one of the best on the market IMHO.
Just google "Why run hot plugs?" You can damage your engine with hot plugs if you do not use the correct heat range....if it is too cold, you only foul your plugs. So better to stay on the colder side IMO
