Few questions. Does the LML switch on the fly? I have had an LB7 with tuning from duramaxtuner, LMM with tuning from ATP and now I have an LML. Any recommendations between Kory willis, duramaxtuner or ATP? I am going to install a FASS titanium and run it stock for now but will do the delete soon so would also like somebody that would do tweaks and changes for free. Kind of on a side not any of the tuners leave their tunes unlocked? I like to learn and do tweak myself but am pretty sure they all lock them now.
