I’m sorry still a little confusion. What exactly is the difference that you can feel when you have both of them on 93 octane? Is it the difference that they both make when using 93 octane over 91 octane? Or is it that when using 93 octane one of them is noticeably better than the other?I will say, using the JB4 on 91 on MAP 3, you could feel the hesitation. I dont feel that with the CAT 6 but when I have 93 on both, you can feel the difference
