Hey. I am new to the forums and would like to ask a question. I have a 2011 2500 4x4 megacab diesel...H&S minimax with turbo back delete, s and b cold air..Was thinking about the overdirve software and was wondering what you guys have seen as far as fuel mileage once installed? Up/down/ or the same?

 

Is yours an HO model? and that would be an 11.5 model year or later. I have an early 11. Cant really tell you about any mileage gains but I like the way it shifts much better and it stays out of 6 gear until your up to around 52-55 mph. I know the HO trucks dont like it, at least a couple buddies of mine tried it and took it off their rigs. Good luck.

 

It is not the ho...just a 2011 megacab with 6.7..

 

I sidnt notice a fuel mileage difference when I put it on my truck. I do like the firmer shifts though.

 

thanks Hoss

 

I don't check mileage anymore but I do love the trans tune and wouldn't be without it.
