I was looking at the DIS web site and noticed that they have the Superchips for the PSD and V10 on sale through July. If you're interested: http://www.dieselpage.com/schip.htm

 

This is from the manufacturer running a special for a short time, which has since elapsed, so they probably still have some of that lower-priced inventory on hand still. We'll of course match that short-term special price for as long as they offer it. Our normal everyday pricing is lower than theirs for registered F-150 Online participants.

DIS is an excellent company with a great reputation for these PSD's, and I'm sure anyone dealing with them will be well pleased. Anyone looking for a real diesel expert would be well advised to talk with DIS.
