I'm looking for a chip for my eta, and was going to go with the Jim C., but many people have said that the Mark D. is better. Is this true? If so, in what way, and by how much? Thanks.

Mark D's are cheaper, and just as good if not better.
If you have access to 93 octane all the time he also makes a chip to take full advantage of it where as the other guys only offer chips tuned for 91.Tenured Automotive Service Professional - Avid BMW Enthusiast

I would love to see a comparison between the Jim C. & Mark D & Ebay chip. i wouldn't be suprised if they were all within 1-2HP of each other. it would be interesting to see the results. i wish someone had the time and resources to do it.Comment
