    2006 lm7 5.3 to lq4 6.0 swap help

    I have a 06 Silverado with a stock lm7 5.3 and i just swapped it with a stock lq4 6.0 from a 04 Yukon Denali.
    My question is could one of you with more knowledge take a look at my tune and tell me if i copied over everything needed from the 6.0 tune to my 5.3 ecu.
    I have done the basics before like removing brake torque management and remove vats but would like to get a second opinion to make sure i copied over everything from the compare function.
    i have attached my as found file and stock file from the 6.0 as well as my attempt to copy everything needed. I have not touched my transmission portion because the truck currently drives fine so dont want to mess anything up there.
    Using all factory items off the lm7 including intake.
    Thank you to anyone willing to take a look and help out.

    Return the electronic throttle settings back to stock, the DBW stuff is different from 2003-2005 and 2006-2007.

    Other than that, it looks pretty good.
    2016 Silverado CCSB 5.3/6L80e, not as slow but still heavy.

    If you don't post your tune and logs when you have questions you aren't helping yourself.
