Re: How many have Shorty wires ? and some questions...
I've had the Taylor Shorties on my Hemi LX for over 5 years now, with no problems. To answer your questions though:
1. You'll only notice a difference in fuel economy if the existing long wires are old and have higher resistance than normal....significantly more than ~12000 ohms for a 3 foot length of stock wire.
2. There will be no difference in the operation of the MDS, again unless there was an engine performance issue prior to installing the shortie wires. You may want to consider installing an MDS "ON" Light that I came up with back in 05, over on the LXForums.com. It's under my screen name, "magnuman" over there. The wiring is the same on the WK Hemi and the install is actually a lot easier than on the LX. Here's the link:
3. No problem using the Superchips or the Diablosport tuner. I use both on both my Hemi vehicles.
Hope this helps you guys out.
