I know this a popular question, but the system is down! I think I read where thay should be .040 is this correct? No room for mistakes on a Lightning. Thanks for your help

 

That's what Sal told me. .040

 

In my opinion it totally depends on your mod's. .040 is a safe number. .044 is ok for 3 or 4 # of boost, if I were to go to 5 to 6 # I would close the gap down to .035. This is another call that the owner has to check out because of climate and altitude.

 

Thanks alot ! I will go with the .040. I'm cautious all the blown motors. I have already spent 3000 on my front yard on gardening I don't need a 30,000 water garden!
