Here is a video of a 600+ HP with over 1200lbft of TQ 6.7L cummins dually. Can you make that kind HP on the stock turbo cause I didn't know that after market turbo's were out yet for the 6.7L. And there is something missing from the video SMOKE! first time I have ever seen a 600HP deisel dyno not spitting out clouds of black smoke. ENJOY!

nice. . .I read up a little and come to find out it is a competition truck. . .so it has to be an aftermarket turbo.
