This is a HUGE step for the Duramax performance market. An 03 Duramax hit over 1000HP on a dyno in Danville, Indiana this morning and it did it on #2 fuel only in a daily driver. This truck has a full built motor built by Merchant Automotive in Michigan (MA) and runs compound twin turbos built by Maximized Performance in Idaho(MPI). The truck is a crew cab short box and also has twin CP3 pumps built by MPI. He runs a full built ATS Extreme transmission with the ATS Co-pilot to put the power to the ground. The truck is tuned with EFI Live. Track result will soon follow! The year of the Dmax has arrived! The name of the rig is Nasty Girl.
