No, this is the truck that dynoed in las vegas, 2wd. I had the tuning for NOS. Its way too smoky for diesel only. The first run didn't have the power all the way up. I think its important to warm the truck on the dyno with a good diesel only run before adding the rest of the fuel and NOS. Those cylinders need to be warm to make and hold power. I think the drop in the graph came when the tires broke loose. It was pretty crazy, people were running for their lives. The power comes on so fast with the NOS. I need to run a bore scope and see what rods are in this truck. Its got 56K on the original short block. I think the reason for the short block holding is because some early low HP 03 trucks had the old 24V rods instead of the cracked, powdered metal rods. Truck still keeps on running, I'm real happy with it. It was a lot of fun meeting new friends in ID, sorry i had to roll so fast, 750 miles away and i still wanted to check out the Cabelas in Reno.
