New to the forum. Just figured I'd make a thread. I went to Sheid diesel ex and dynoed on the Dp tuner dyno. Made 536hp 870 tq which tq seems low. I figured 530 so not disappointed. I'm running 180s not sure nozzle size RCD did them. Been looking at the barder turbos since I heard someone made 620 with one. With 410 gears but still impressive. Anybody got some info?
