Attended my first dyno day ever. Hooked up to the dyno at diesel thunder in Spokane. Ran my LLY on the rollers for a 532HP on #2 w/ IdahoCTD twins. Thanks Nathan for making this truck a blast to own. I get a rise everytime I get in it. :bow:

I think the elevation is around 2100' in Spokane, WA but dont quote me. The outside temp was in the low 90's. I didn't catch the correction factor or if they were running one. The dyno was a Dynojet 248c with the lighter rollers. It's pretty hard to get things rolling when you cant load the Dmax's. You have to ease into it at 2000rpms then mash it about 2300 to keep it from down shifting. The torque numbers are a little low because of it also. I think Rob only did 979ft/lbs. Once we can figure out how to hold it in 5th and drop the rpms numbers should go up.

Hey Slowford,
Wanna take a guess at what it will lay down?
Lets make it a contest to see who nails it.
I say 430 unless you have more mods than your sig shows
Hey nummit, I hope it makes that. I got a tune yesterday to lock trans in 5th to get the right numbers on dyno. :)
