H&S has tunes for the LML as and bullydog is in the final stages of tuning the LML too:toytruckI'm jealous, They have a programmer for the 6.7. I do miss my EFI Live tune LMM with a DSP5 switch and built tranny. I keep telling my self I'm going to keep this one stock to pull my camper. Well, It's like a illness. I love diesel performance.
