Default FI and Sparkplugs??
You guys out there with SC's or TT's, what sparkplugs are you running and what are you gapping them at? I figure I will be bossting about 12lbs max. Do you have to reduce gap because of the extra air flow?
Thanks, Dan

I had already picked up the TR6's but I saw another thread started on the TR55i's and a 50 - 55 gap. Thought that was a little big but just wanted to get a general idea what the FI crowd was running! thanks guys!!

TR55 is the stock heat range and .050 gap is too big unless your running MSD's new higher output coils. They say you can run .050" on them.
