More timing yes. Although my 18 with just a e85 tune smokes my old 14 w/ cj and bolt on’s.Thanks! Were you able to tell a difference?
Boostane and ethonal free 93. It was probably a bit over 100 octane as the tune started pulling fuel.Good stuff! Did you use Boostane or something else? And what was your starting octane? 91 93?
