Help me tune my dizzy?

With a 4 speed and 3.55s, I might consider slowing it down some from all-in by 2000-2500. You don't have the luxury of the TC.

I ran a similar combo with 28* at 2800, and all in by 3400. I ran 87E10 set up like that. I was running 10.9 Scr tho and 8.6Dcr corrected to 1000ft.
At your compression ratio tho, you might be able to getaway with TrailBeasts start recommendation. But I like to sneak up on it.
