I guess this should probably be in medium duty but thought i would try here. Just wondering what is the real differece between the LMM and the LYE. I know the LMM is in 3500s and the LYE is in some 5500s.
The reason im asking, Im needing the edge box with attitude desperatly. To my suprise looks like edge doesnt even make one for the LYE. Has anyone out there tried the edge for LMM on an LYE ??? Thanks

I would take this question to the Medium Duty Truck Section and see how many of those guys know. Ive personally never even heard of the LYE.

I never heard of that either. Although a quick search yielded it is an LMM with a different calibration called LYE. There is also an LRX option, apparently these are only available on the TopKick medium duty trucks. BTW, these options LOWER HP, not raise it. LRX = 300 HP / 520 TQ and LYE = 330 HP / 620 TQ. I can see why you are looking for a tuner...

I have a barely used Edge Juice with Attitude for the LMM for sale if it will work for you! Send me a PM or e-mail.
