I agree... I thought you meant you would NOT run a non-projected tip plug...I must have misread your post... I was like WTF...?
I wouldn't even start with a TR...(projected tip)
I start at a BR7EF and go colder from there... I usually end up in the 8 range up to 900 ish on pump/meth. Lots of variables though.
