He was familiar with both the sert and the power commander, and explained them both as if he read this forum, HA-HA.
I have the HD hi comp cast pistons, 211 cams, up graded HD springs, comp releases, V&H Straight Shots and what I was told today that the guy that put my motor together down loaded a custom map into my ecm.
The reason for the dyno run was that I installed thunder monsters and could really feel a differece but wanted to see if it effected my fuel ratio.
I gained 5.2 HP and 1.63 TQ but it moved the curve into a more usable area
without effecting the fuel ratio.
They worked just like the lady that sold them to me said they would and they sound great.
He sold me on the sert and I am having it installed later in the month.
