This is the baseline dyno run for the DT headers Install. We are scheduled to make the followup run 9/8/2011. Headers will be installed 9/2/2011 and I will attempt to put some break in mileage on them before the second run.

The Mileage figures represent when the last service was done. Items listed are for contextual purposes to better understand the state of tune this truck is in and how that could effect readings. Please keep in mind that every single dynamometer will give different numbers. These numbers may appear high or low depending on your side of the fence. That isn’t important. The value of these results and comparisons should provide information on the relative difference adding the DT headers to a stock truck can make.
