I was talking with the owner of a local speed shop. He told me a story about a customer with a Ford Deisel Truck that was chipped. The guy decided to try to race someone while towing his boat and lifted the heads off the block.

He pulled the chip and took it to the dealership. The service dept hooked a computer up to the truck and could tell the fuel, timing and boost had been altered, voided the warranty.

The guy had to buy his own engine.
