Seeking a stock compatible compare file please and thank you

[Boost]

Greetings old (and new) friends. I am SO delighted to be back after so very long. I woke up to the first beautiful and heavy snow this morning at our new location. Back on topic:

I am seeking a stock compatible compare file please and thank you. Just took over sorting a co-worker / supervisor's personal truck and there are some very basic and minor changes I need to make to it. But first I'd like to see how this current mystery file differs from stock. It starts / idles / drives - just not very well. We've gone over mechanicals and I'm ready to fix idle, takeoff and shifting hiccups. This will be a great way for me to jump back in and get in the boss' good graces at my new job too haha. Thanks and I hope all are doing outstanding, best wishes for '25 !!!!
:cheers:

Thank you! It's a 5.3 essentially I just need a compare to see the mods to the cal. I think you can only compare same OS, am I correct? I could always do it manually. And for the record it does NOT have a good or locked tune in it. I can do way way better, just haven't done this in a decade LOL! Thanks for the replies and the help !!!

With V8 you can compare anything you want. It doesnt have to be the same OS.

So I need a compare file of a USA based 5.3 liter "3" motor (8th digit) with a 6 speed transmission (T43). All I'm finding online so far are Australian "Y" motors.

RPO code "LC9"

Looks great, thanks much! Even though it's a 2011 to a 2009 and thus newer calibration version, I am sure the hardware is the same. I was successfully able to compare both sets of files which was the goal. Awesome, now I just need to figure out which differences are manufacturer updates and vehicle differences, and which are actually aftermarket tuning modifications. Good deal, I appreciate it!
