I am doing a speed density tune and running E85. I have bigger injectors now (was 42lb, now 60lb) that will be 72lb with my bigger fuel pump.

Should I run a hotter plug than my previous plug, NGK TR55?

I have a bigger motor, crank, heads, intake, TB, etc..... than my previous stock bottom end with heads & cam. Was making 420 RWHP, hope to make over 600RWHP.
