I have one in my 07.5 beta testing it. The power is there for sure. First tune loaded was the performance setting and I was shocked at the difference in power. Engine was alot louder due to the timing and injectors but i liked it.
I tried the towing setting next and it was a little bit quieter and still had decent power. Now I have it on the economy setting seeing what the mileage is going to be.
I have yet to try the highest setting and I most likely won't. I noticed a TC shudder one time when I had her pinned back on the 85hp setting and I got nervous. I am sure it's ok but i didn't want to push it as I only have 5500 miles on it. Overall I am happy with it on my LMM, I would think it would be the same on your LBZ LLY, better infact you don't have the dreaded DPF filter that I have.
I know if I come upon a Tundra or Titan at a light I won't be worried :Thumbup:
