Just got mine dyno tuned. Truck is in sig. From what I was told on here I should have way more power then this. I trust my dyno tuner. But why was I told id get so much more power. Magnuson clames 120hp by just bolting on the sc @6psi This was in 3rd gear so there a little low. Is there any way to find out what they would have been 1:1

That looks to be about 425 to the wheels? (I'm on a cell)

Haven't had mine on the dyno yet. Might spend the money for a few pulls this summer. Will post up when I do.

I am surprised at how the torque falls down like that. It should fall off, but that looks like it is a little much. A restrictive exhaust or air intake can make that problem worse. The 6.2 heads really flow some good air so that shouldn't be a problem. A cam would help with moving some air.
