and I am on the 65hp tune. It just does not feel any different than before. I thought there was suppost to be a noticable difference. I will drive it a little more this evening and see what I find.

I dont see much difference than stock with this thing. What is the deal?

Ok, I will try that as soon as I get the cable. The main thing that I dont understand is why this thing worked in the past for the previous owner. Can you explain why that is? Thanks for the reply! -Tanner

anybody out there?

It says v8r14. Is that what you are talking about? Thank you for replying!

I bought a truck this past weekend that came w/ the diablo u7165. When I plug it in to do a tune it says "your vehicle is not in our database. contact your dealer for a free update. you cal_id is 'vxcf5h5' " what do i do??

The truck is a 2006 f250 powerstroke any suggestions?
