Ok, sorry about the size I'll get it right some day.
Anyways just to make things clear this is from a Dyno Dynamics
and those results are Green. The Red lines are Dyno Jet numbers.
Any thoughts or opinions?

Just so I'm clear, the one line is a DD dyno, and the other is a DJ dyno, and its the same motor without any changes ? If so no wonder everyone laughs at the DD numbers being posted. 75 rwhp difference is huge !!!
Did you change your post or did I forget reading comprehension? So now the DJ is the one with the huge numbers and the Dynamics rated your stroker at 450? I'm a bit confused, please help me out. LOL.

I don't understand why they are different either.
The DD is a load bearing dyno unlike the DJ's.
Maybe someone here can explain the deal.
Guess I shouldn't have posted the dyno sheet after all.

I guess I'll in a couple of weeks when the local Dyno Jet is up and running again I'll see if the "corrected" numbers I recieved from the DD were calculated correctly.
The tune however looked good. A/F was at 13.0 across the board on WOT
WB at the Borla tailpipe. It produced a little KR up top so we took out a couple deg of timing and stopped there for now.
Regardless of the dyno numbers legitamacy I am pleased with the performance at the track as this is a new motor and I was running on a base tune I created from my old setup.
I have some exhaust changes coming and suspension mods to do so hopefully I can hit mid 10's on motor.

yeah jims dyno is a load bearing one,and it can humble you,but at the same token when the conversion is made to be dyno jet numbers on the dyno dynamics its on the high side..
but its a tool for tuning..if it runs well thats whats important..You could put it on jeffs dynojet to compare..I'd be curious myself the difference between two diff dynos
