Bully Dog and power chips do they work on gas engines

Check out 5 Star Tuning. They are THE people to go to for tuning the Ford V-10. I have one on mine and it works very well. You can get them in any octane rating you want. I got mine for the improved shift strategy over what the factory programmed in. I did gain almost .5 mpg, which is not why i got it, but it was a benefit. It will also add approx. 25HP AND around the same in TQ.

Very very excellent reputation!
