2016 Chevrolet Silverado 2500 HD

The witching hour arrived and it was time for the 2016 ‎Chevrolet‬ ‪Silverado‬ HD with the ‪Bad‬@$$ 397 hp and 765 lb-ft of ‎torque‬ monster 6.6L called the Duramax‬ ‎turbo‬ ‪diesel‬ to prove its prowess. The aFCD offset was calculated during the calibration run the other day and now it is time for some very early morning Interstate Steady States. A fresh 2L of Pepsi‬, a notepad ready for data, Pandora on an unlimited music streaming T-Mobile acct., and a super truck. Always interesting and you never know what the results will be until they are complete a few hours later...
