I broke mine in on my 60 horse stock trans tune, drove it a week like an old man, got built trans tunes, put it on the 150 tune and did a few stop and go runs through all the gears until I ran it wfo, beat the **** out of it every since.
I broke my LLY in on the 120 tune, it would shift hard one time and slip the next for about 150 miles, then I went on a drunken rampage and it was right and tight.
My LLY would bark the tires on the 1-2 shift at 3/4 throttle, it was an aggressive set up, I actually liked it over the LMM, it's smooth and crisp but doesn't like the rough housing like the LLY did.
