2011 Silverado TVS 1900 Dyno question
2011 Silverado 2500 6.0 TVS1900 with ported 2300 lower tub and 3.2" pulley. So I got my truck dyno'd and obviously the 3rd gear pull is the 1:1 ratio, he would not do it in 3rd because he says these trucks will lose the driveshaft at the top end of 3rd because they are unbalanced. The truck did 362rwhp in 2nd gear, any way to calculate what that would be in a 3rd gear pull? The number just seems low to me. It was done at 8lbs boost, where under load on the highway I can pull 12lbs.

Your truck is actually 1:1 in 4th gear with the 6 speed trans. A second gear dyno is going to read very low as you pointed out. He is right that its common to toss a driveshaft at the top of a 1:1 gear in a big truck.
Interesting that boost was low though. I can see it maybe being a tad low on such a short pull, but 4 LBS is a ton.
