473HP on stock truck

[mstordahl]

Got to put my truck on the rollers today at an annual dyno event and laid down 473 with a nice smooth curve. Held that power right to 3500 where he let out. I know its not a lot, but the truck is stock other than a trans and I tuned it myself so I am happy. Just wanted to share what is possible. I also drive this tune all the time and it is very well mannered with no smoke. Just simply cannot beat EFI!

Oh and this was my first dyno with EFI, no dyno tuning... Yet!

Nice. Is that BONE STOCK? As in with the cat and muffler in place? And stock airbox?
Just curious. Trying to compare numbers of what my truck made on my buddy's stingy dyno back when I tuned it with the Smarty. Thanks for the info.

All my truck has is the DTT trans, no cat or muff, and an intake. Nothing else, no lift pump even. This is cool, seems to be right in line with what oters are making.
