best plug

[USMC_Turbo6]

What is the best plug to run with E85 and what should the gap be set at. Also will running a TR6 make a big deal with setting the gap for the plug?

Hard to say since you have that fancy ignition box. Ngk 6 or 7 heat range. Try those.

I have had good luck with the NGK. Try them out. Remember, E85 reads lighter than regular fuel. I bet the 6 is a good starter for you. Then the 7 for high boost. I ran an 8 too but the 7s were fine at boost levels waaaay past the 29 mark.

Ive been running NGK UR5 gap at .028 I am thinking about trying to open gap up next time At track.

Are AC Delco CR 43TS okay for E85?

You can start out with those. I use a colder NGK plug when going past 24psi. I have to look up the part number.(winter memory)
