His truck is bone stock with 10,000 miles. He complains about the mileage and says it gets 14 mpg empty. He also complains about the slow and slushy shifting auto. He wants better mileage and better shifting. Any suggestions? If I could resolve just one of the issues that would be OK. Looking to spend around $4-500. If some performance modules could add power and mileage, even better.
