7875 + 5.9 + E85 + Megasquirt

I didn’t see the reason why you posted your cam specs again. Maybe I missed something?
Dizuster originally had a (small)reverse split cam in his car with which, I believe, he still ran low 10’s around 135+ @ 3700lbs. He received criticism from big names and eventually switched to a custom split cam specked by Lil John who is I’d say an expert with turbo cams. The cam made almost no difference, and also failed to rpm past 6k despite a complete valvetrain revamp.
Are you thinking about switching?
I would think dropping in a gen 2+ 7875 would make the biggest improvement if you’re after a power increase
