I've tuned em all from 01-10, and I still prefer LB7's. They just do what you tell them to do, none of this guessing crap and dealing with 20 different multipliers to get one table to do what you tell it to. Or ghost codes that pop up for no reason, any of the other issues BOSCH ECM's have. Or LLY's that pick and choose when they want to flash, and if they take a flash. LLY's are honestly worse to do than BOSCH ECM's IMO. I have pulled my hair out more with LLY's trying to get flashes to go in, or take than any others combined. I've got one truck in particuliar that I have lost count of how many times a flash said it went through, but afterwards the truck just didn't run right, or tunes being in the wrong position. Reflash it and sometimes it will go through and work fine, or sometimes it goes back to stock. I have REALLY come to hate LLY's.

I agree with lly's being a problem child. Once you get the correct os the correct dsp5 upgrade and a relm of hardware changed out you have a good running truck.

I'm just tired of chasing my tail on this. Been through 3 different tunes and a bunch of other stuff. First two were positive it was a boost leak and so on.

I set the cruise on 60mph, let it start up a pretty decent hill that loads the engine pretty good, downshifted to 5th in manual mode with no problem

Could be. Mine started life with an A50 but now has an A40 from an 07.5

You did that bc the a50 wasnt cracked yet though right? I dont think it is a problem with the tcm, its ecu related. Have you ever had any wierd issues (ie low boost codes and excessive smoking) with your lmm?

Mine has played well too. Oddly, efi live says I have an A40 tcm in my 09. How can't this be?
