I owned my LML for over 6 years and the only trouble I had with it was the smog crap and bad TCM. I didn't delete it as I didn't know how long I would have it and I live in Calif.
With Rob's tuning I had no dead pedal and could blow the tires off the line at will. The truck was great. IMHO, delete the smog crap, replace the CP4, and a good tune you would have a great truck.
