3/4 trim? On a scale of 8, 1 being buried, 8 being a little below trailer, my Heat likes it best at 3. And that is blowing quite the rooster tail. Man I need a spacer thus winter. 20% slip is way too much for me.

How is the 28 out of the hole? I hit the limiter also trimmed up about 3/4 but cannot get past 74. Would like to try the 28. Did you also do the whipple tune?

I forgot you don't want to do the whipple tune. Would you do the CMI's again or would you try another header?

My girl has a bit of blow out on the hole shot. Definitely needs a spacer.

I was going to go with lightning till I realized they had to be custom made with the 60 degree bend in the collector for our tip location, price was equal to the polished Cmi stops, which were also all stainless in and out opposed to the lightning, I had Dana's on my old 454 and they are great too, but aluminum

On that scale, my stock 26 was 4, and this 28 would be 5-6, its much higher than I have ever run before, but I was a full mph slower with it at 4
