Bully Dog power Pup and my experience

I know, but when I scanned the ECM it came up with a stock MBN file according to the guy I had scan it. So I figured I could do better with a tune since I run empty basically all the time. I mean a empty flatbed weighs almost as much as I do loaded!

I also think I may have found another problem as I had moved up my 5th wheel when I was running liquid tanks last month and did not move it back for my dry bulk tanks. I moved it yesterday and my EGT and boost pressure went down quite a bit. These dry tanks like to be put almost to the last hole in the slider. My boost was at 4-5psi again which is the same as when I bobtail.

 

That is why I went with the BD tuner. I can transfer and use it on any electronically controlled CAT motor and if I buy another truck without a CAT I can just sell it and at least get some of my money back.
