I had this work completed at HD of Fargo. I had them do a dyno run with the stage 1 gear on just for comparison. I was a bit surprised that the numbers were as low as they were but still in the ballpark I guess.
Keep in mind on the "after" that my instructions to the shop were to attempt to flatten out the torque curve as much as possible during the tune within the restrictions of the tuner. This has the wide band O2 installed.
I also had adjustable pushrods installed (details matter!)

 

I bet she feels much stronger, it's the ride that counts not the numbers .

 

There's 3 feet of snow in my front yard and it's -6 out right now. But she looks fast!!

 

What is a Stage III, exactly? what parts?
