I just bought my truck about a month ago and now its missing. I am pretty sure its the plugs. The former owner told me that ngk tr6's were in there and gappped to .035. I see between 15-17# of boost wot. Should I go to a colder plug because he said he had recently changed them so they shouldn't be bad this fast? This chart makes me think I may need to go to a colder plug because of the boost im seeing.
