Doug,
Before you spend anymore money on dyno testing, call Demon. They have a great tech support line. Tell them what you are doing and fax the info to them. They will call you back with suggestions.

Here's what they told me:

1) Change linkage from progressive to one to one. $ 7.50
2) Put 1" 4 hole spacer between carb and manifold $ 20.00
3) Adjust linkage to make sure you are getting full stroke (Free)
4) Jet down 2 numbers (I bought jet kit) about $ 30.00

Result: 60 hp gain
