Dear Tom,

I own a 2006 F250 4x4 Ex Cab with a 6.0 L Diesel. What are your thoughts on the chip tuners such as Bully Dog and Super Chips? Are they worth the investment?

Douglas,

Dear Tom,

I own a ’02 Ford Focus that came with one key when I bought it (used). When I went to get a second key made I was told that they couldn't make a key for it because it had a “transponder” and I would need to get one from a dealer. This is expensive! Is this absolutely necessary or is there another way to get a key?
