Stacks & Chips = Fire
A friend of mine just sold a bunch of round bales to a hobby farmer about ten miles from home. They were delivering the hay on a gooseneck trailer behind his boy's 99 F350 with straight pipes to stacks and a tuner chip. His boy headed out with a load, clicked the chip up for power, smoke, and sparks. Then about a mile and a half down the road he had a couple of flaming round bales. He pulled her over unhooked the truck and got it away. He happened to be in front of a truck shop and the guys came out and helped get the load untied while somebody got a backhoe. They were able to push the burning hay in the ditch and save the trailer with only a few burned floor boards. The local fire department hosed the burning hay in the ditch. After it was about over the state police showed up and ripped on them to get that stuff cleaned up in the ditch. It was a good half days time cleaning up the mess. Now the boys stacks aren't near as tuff as they used to be.
