Outstanding!
Maybe the gains aren't as much with the other chart because of both on e85. But with this chart with an old truck mamifold, it makes more power and a lot more at times up to 6700. I've got no problem with that on the street. You constantly busted on the op for afraid of 8000 rpm. Well I'll tell you, I am.all the tq and then fall on its face when the coyote wants to rev past 5k LOL!
