This chip will work with F150's with the 4.6 and 5.4 engines. Will not work with the ecco boost engines. I used this only once. It is still in box with all the instructions. This chip cost me $399.00 plus tax when I bought it. It can increase your hp plus increase gas millage. I was told it was one of the best chips on the market. My gas millage increased by almost 2 miles per gallon and I drive in town alot. I'm sure it varies with the type driving you do. I really increased my horsepower by over 15hp. I would recomend this chip to anyone. The cost includes shipping. Call me if you have any questions. Remember your hp and fuel economy may vary from automoble to automobile depending on your driving conditions. Phone # 336-922-5009
