I have been following this thread with interest. According to the owners manual, the recommended gap for my 2010 is .033-.037. I checked the manual for a 2013 SHO and found the exact same recommended gap. I understand going to .030 if you are running extra high boost levels, meth, upgraded turbos, etc.
I am just running the 2012 version of LMS stage 4/93 octane. I might try Torrie's tune at some point but have no intention of running meth or doing anything more exotic than what I already have. I am going to replace my plugs with SP534s as routine maintenance. What benefit would there be to gap them at .030 versus the recommendation of the manual? Typically, I would expect a larger gap to be better - assuming the coils are strong enough and the boost doesn't blow out the spark. I have no idea what my current plugs are gapped at but I have never experienced a problem with misfires or any other issues.
Thoughts?
