When do you see the full 16 psi of boost? About 4500 RPM?

So am I correct that it basically picked up 100rwhp on the converter swap? Maybe I am wrong, but I thought it was 79xrwhp before??

Anymore thought on doing a cam swap to a JFR? Just curious on if that was still kicking around as a comparison. I personally like the #'s LilJon has laid down, but either way, both guys have some serious #'s in combos.

That's a big improvement for just a converter swap.

It's an Apples to Oranges comparison really. This converter was locked for the pull, the other one was not. Would be nice to see what the new converter does unlocked.

Impressive numbers nonetheless.

A 900hp work truck has got to be the greatest idea Ive seen in a long time. I have always liked the single cab Colorados. I drove one for years when I was in the beer business. Denmah, you surely know how to test parts to the limit. This goes to show that having a really spot on tune, does more for your engine than all the forged parts combined. Too bad you live above the mason dixon line, its mid 70's here in Fl. Be nice to see a mid 9 second time slip.

how much has your fuel tune change between E85 and pump gas? Is it the usual 40% or so?
