Upping the HP on 08 LMM

EFILIVE FTW!!!! Id advise your friend to check out Kory Willis @ PPEI's track record for making great power on stock trucks(smokeless).
 
I was a bit cautious on the EFi as well so I ran what I could find for a decent cost, I later found that it just wasn't working for me and wasn't what I truly wanted. I got EFi'ed this weekend and fell in love with my truck allllllll over again. Don't hesitate, just go EFi.
 
I have the duramileage EZ tune on my 2009 with DPF delete, and EGR delete program.
I have stock, 60hp, 80hp, 100hp tunes.
I am getting 18mpg on the 60hp tune, and now I am trying the 80hp tune!
So far I like it a lot.
