Spark plugs gap and misfire
I´m runing 14-15 lb in my car , and have some misfire problems at wot, I have denso iridium sparks IKH22 gaped at 0.8mm.What is your spark plugs gap , for you guys that are runing 15 or more lb????
I have a flat 11:1 AFR at wot , maybe this is causing my misfire events , but not sure , anyway I don´t want to change my AFR because I like the safe side....

the stock heat range (5) and the cooler (6) plugs both come with a .11 mm gap (.044")
