I know there is a lot of threads in this forum about the diffrences in LLY and LBZ but I have another question. I have an 06 LLy with an edge juice w/ ***. installed the rest of the truck is stock. I have read that the only diffrence in the 06 LLY and 06 LBZ is the programing. So what is the max setting that I could put my edge modual on. The way I think of it if I put it on Level 3 which is 60 hp I am right around LBZ hp. Edge says that level 3 is what you should drive in. But if the LLY is just de-tuned then I could safely run a program with + 110hp.

I know it sounds confusing but I know someone will make sense of it all.

I asked the same thing about a month ago. I think you asked more clearly than I did - maybe we will get better answers. I have been working my way up and letting the tranny learn and I am now on level 4. It is nice and my milage seems good so far (have not run a tank thru yet). I may leave it here and turn it up when I want to smoke someone on the hot setting!!:D
