[QUOTE="Groovy Chick, post: 245893, member: 1756"] As per Bill (he can't get to the computer): It was our impression that the only vehicles affected were 7.3Ls using a particular chip. Based on your experience, it is possible that the noise concern caused by certain HID kits may be a much larger concern. Yours is the first NON-7.3L vehicle that has had this issue. As for the old 4 position chip, having an occasional stutter can still be attributed to RF interference due to a poorly shielded cable. We haven't sold a 4 position chip since 2003 or so, and we are not aware of any of the 6 postion chips having this problem. There are definitely concerns with specific HID setups with lower quality ballasts running higher frequencies to compensate for smaller tranformers. These higher frequencies seem to be directly linked to the interference. However, proper signal shielding can alleviate many of these problems. One of the things that we've learned over the last fourteen years (when designing electronic components for automotive systems) is the importance of quality shielding to avoid problems like you described above. Thank you so much for your post! [/QUOTE]
