I have recently been getting a check engine light and while I would like to check this out and clear it i would also like some additional information. I am looking for advice by way of actual user reviews as to which one is best and why.
appreciate there is a reasonable cost difference but I am open to advice.
Also can these be changed from car to car without modification, I fell the scangauge can but unsure as to the specific nature of the Bully Dog. They also advertise an additional pyro probe - is this needed?
thanks for your help
