Hi,
I just installed a ec harness and am putting on a new Mac system, headers and mufflers. I am running factory jets and plugs butam wondering if I should change jets and plug heat range. I don't know a formula to help figure out what plugs to use. Is there a formula to help figure this out or has anyone made similar changes.
thanks Tim
